Alemtuzumab is a drug used in the treatment of chronic lymphocytic leukemia (CLL), cutaneous T-cell lymphoma(CTCL) and T-cell lymphoma under the trade names Campath, MabCampath and Campath-1H, and in the treatment of multiple sclerosis as Lemtrada. It is also used in some conditioning regimens for bone marrow transplantation, kidney transplantation and islet cell transplantation. It is a monoclonal antibody that binds to CD52, a protein present on the surface of mature lymphocytes, but not on the stem cells from which these lymphocytes are derived. After treatment with alemtuzumab, these CD52-bearing lymphocytes are targeted for destruction. MabCampath was withdrawn from the markets in the US and Europe in 2012 to prepare for a higher-priced relaunch of Lemtrada aimed at multiple sclerosis.
The KRIBIOLISA™ Alemtuzumab ELISA is used as an analytical tool for quantitative determination of Alemtuzumab in serum, plasma and cell culture supernatant.
The method employs the quantitative sandwich enzyme immunoassay technique. Antibodies to Alemtuzumab are pre-coated onto microwells. Samples and standards are pipetted into microwells and human Alemtuzumab present in the sample are bound by the capture antibody. Then, a HRP (horseradish peroxidase) conjugated anti-Alemtuzumab antibody is pipetted and incubated. After washing microwells in order to remove any non-

Dr Jayaraman D. Lead Scientist, leading CRO company
I have been working with a team from KRISHGEN on an assay development and customization before giving us. The project was complicated and needed technical expertise in immunology. I was very pleased with their technical competence and also mastering immunology and delivering a tough project to us on time. Their rigor, punctuality and expertise have been a recipe for the high standards, I would expect for such project from them. Kudos, Krishgen Team!!!
Mr Ramesh Sravanan, VP-Supply Chain
The expertise and command on the logistics chain including the regulatory
guidelines from Krishgen is something we admire. As they often indicate, let us
do the supplies, and let your team focus on science … is really something the
company works on. Delivering consistently, with less than 1% error or delay
consistently is the key to their success.
Dr Keith Stevens, visiting Scientist, Norfolk University, UK
To have a company understand science and work with them, is a pleasure. Krishgen
not only sells but understands what it sells in terms of the complex cutting
Mellisa Karlowski, Lead Researcher, east coast US CRO
The company is good on understanding its customers, is transparent and
speaks science. This makes it easier for us to work with them.
