Summary of the impact
Professor Neil Barclay and Dr Nick Hutchings established Everest Biotech
Ltd in 2000 in response to the increasing demand for high quality
antibodies within the research community. This successful spin-out company
has since become a major power in antibody research and production, a
position reflected by its portfolio of more than 6,000 antibodies
recognising human, mouse and rat proteins, and the generation of 60 new
antibodies each month. With offices in the UK and Nepal, Everest Biotech
Ltd also benefits one of the poorest communities in the world by providing
additional income to hundreds of farmers in the Nepalese foothills.
Underpinning research
Modern research continues to identify increasing numbers of proteins and
the ability to study these molecules at the single cell level is crucial
in order to identify and understand their functional roles. Cell surface
proteins play important roles in communicating between a cell and its
environment, and are thus involved in fundamental cellular processes such
as signalling and molecular recognition. Structural analysis of these
proteins is complicated because many are embedded in the cell membrane.
The study of cell surface proteins therefore required the development of
methods to express soluble forms of the proteins in mammalian cells; these
soluble forms had to be correctly folded and glycosylated. In 1993,
Professor Neil Barclay in the MRC Cellular Immunology Unit at the Dunn
School of Pathology pioneered an approach to achieve this goal whilst
investigating the biochemical nature of proteins on the cell surface of
leukocytes and their role in immune regulation1,2. The approach
was based on the expression of recombinant chimeric proteins that were
secreted from cells. Because the secreted proteins could be detected with
antibodies that recognised the known `carrier' portion of the chimera, the
new technology enabled rapid advances in our understanding of
receptor-ligand interactions and accelerated the X-ray crystallography of
immune receptor molecules3.
The Barclay group subsequently applied proteomics approaches to screen
all proteins involved in functions on the cell surface, rather than
concentrating on selected proteins. Using mass spectrometry techniques
they identified the many proteins involved in transmitting signals from
the cell surface into the cell. This advance meant that higher-throughput
technologies were needed for subsequent functional analyses. To this end,
the group has remained at the forefront of developing assays for studying
protein interactions, including protein microarrays and high-throughput
screening for ligands using microarrays4,5.
In 2000, Barclay realised that, given many of the chimeric proteins were
also powerful immunogens, this provided the opportunity to generate
antibodies against large numbers of correctly folded soluble proteins.
This opportunity was commercialised in the University spin-out company
Everest Technology. Ongoing research in Oxford supports the company and
maintains its focus on high quality reagents against proteins that may be
a focus of future interest. This forward thinking facilitates the fast and
efficient study of new proteins as and when they are identified. For
example, Everest's antibodies to FOXP3 protein were available when FOXP3
became of central importance because of its role in immunoregulation6.

Details of the impact
By the end of the 1990s, the Human Genome Project and associated
large-scale projects were fuelling the expanding worldwide demand for
antibodies that recognised relevant target proteins. The development of
extensive new methodology for the production and characterisation of
conformationally accurate mammalian proteins, which had evolved during
work on the role of leukocyte cell membranes in immunity, placed Barclay's
group in an ideal situation to establish a pipeline for the large-scale
production of high quality and reliable polyclonal antibodies. This
commercial opportunity was exploited and has had wide-reaching impacts.
Professor Neil Barclay and Dr Nick Hutchings, assisted by Mr Ravindra
Sapkota and Dr Raju Adhikari (Nepalese graduates from the Department of
Biochemistry at the University of Oxford), developed a business plan to
produce polyclonal antibodies on a high-throughput basis utilising the
combination of competitive production facilities and locally-farmed goats
in Nepal. A Business Angel provided £350,000 and the spin-out company
Everest Biotech Ltd7 and its Nepalese subsidiary Everest
Biotech Pvt. Ltd, were successfully launched in 2000. Hutchings became the
Chief Executive of Everest Biotech Ltd and the Chairman of Everest Biotech
Pvt. Ltd in 2001. Antibodies went on sale in 2002 through a variety of
companies including Abcam and Serotec. More than 6,000 products have now
been produced and marketed with approximately 60 more antibodies being
produced every month. Everest Biotech Ltd also works in collaboration with
researchers to produce custom made antibodies for individual research
projects and more than 200 custom antibodies have been made in this way.
Importantly, the company also provides technical support to its customers.
In 2005, Everest Biotech Ltd began selling antibodies under its own brand
name to customers in the USA, an event that was facilitated by outsourcing
with LifeScience Logistics8. Sales grew steadily without
further external investment to reach £0.49M in the year to 31st
May 20089.
Since 2008, Everest Biotech Ltd has become an important commercial
company, not only making a significant contribution to scientific and
medical communities, but also benefiting the small Nepalese community it
sustains through agricultural support and employment. The success of
Everest Biotech also led Barclay and Hutchings to establish the company
Absolute Antibody in 2012, to provide monoclonal antibodies made by
recombinant DNA technology to the scientific and medical communities10.
Commercial engagement
Everest Biotech Ltd has up to five full-time staff in the UK involved in
product design and distribution with Hutchings as Chief Executive, and 25
Nepalese employed full-time in the antibody production facility at Everest
Biotech Pvt. Ltd. The Nepalese subsidiary has been described as one of the
ten key institutional stakeholders in the medical biotechnology sector in
Nepal11. Everest Biotech has been a major supplier to Abcam
Ltd, one of the most successful UK companies selling antibodies, and
recently began supplying antibodies to Sigma-Aldrich. Everest Biotech
antibodies are now distributed throughout the world under the Everest
brand via companies such as Abcore (USA), Sanbio
(Netherlands), Funakoshi (Japan) and Sapphire Bioscience (Australia and
New Zealand)12. This commercial success has also enabled
Everest Biotech to open a branch in California13.
Everest Biotech is now a profitable company with approximately 75% of its
products being exported. Since 2008, over £7.5 million of Everest Biotech
antibodies have been sold worldwide and turnover in the year to 31 May
2012 exceeded £1 million9. An important role of Everest Biotech
Pvt. Ltd is as an export industry, bringing in approximately £250,000 per
annum to Nepal, an economy that is greatly unbalanced towards the import
of goods14.
Community engagement (social, cultural and economic impact)
As the only biotech company in Nepal providing employment within the
poorer rural communities, Everest Biotech Pvt. Ltd has had an important
social and economic impact on the lives of many Nepalese workers and
farmers. Everest Biotech Ltd uses several hundred goats per year purchased
from local breeders to make its antibodies. These goats are then
distributed to approximately 100 individual farmers in the villages around
Kathmandu who are paid a premium for looking after them, a situation akin
to the establishment of a large number of small animal facilities. One
very important aspect of this support has been that owing to the farmers'
increased income, many children now attend school in these villages rather
than remain at home to help with farm work. The company also promotes
animal welfare at the village level by providing veterinary care and
vaccines for all goats in the community, including those owned by the
farmers as well as those being used for antibody production14.
The employment of 25 Nepalese staff at Everest Biotech Pvt. Ltd in
Kathmandu further promotes the local economy. Many of the staff, after
obtaining excellent training within an industrial setting, progress on to
obtain higher qualifications either in Nepal or overseas. Additionally,
the company provides expertise to the life science community of Nepalese
universities14. Furthermore, Everest Biotech Ltd is the major
benefactor to a number of good causes in Nepal such as The Esther
Benjamins Trust15, which is a UK based charity supporting the
rescue of trafficked children in Nepal.
