The partnership will provide the life science market with an innovative conjugation chemistry for antibody labeling
4 June 2024, Frederick, Maryland. Columbia Biosciences, a biotechnology company based in Frederick, MD, announced a partnership agreement with conjugation specialist AlphaThera for the use of Columbia’s SureLight® R-phycoerythrin (PE) and SureLight® Allophycocyanin (APC) fluorescent proteins in the development of AlpaThera’s oYo-Link® Site Specific antibody labeling range of products.
Columbia Biosciences, founded in 2007, is a leading provider of antibody and protein labeling services as well as one of the largest global suppliers of the fluorescent proteins APC, PerCP, RPE, and BPE for flow cytometry. Its fluorescent dyes and antibody conjugates are used in FDA-approved diagnostics, research applications, and clinical trials.
AlphaThera’s proprietary oYo-Link® technology provides researchers with a quick and easy, site-oriented approach to labeling antibodies for a variety of applications. The technology uses a unique Light-Activated Site-Specific Conjugation (LASIC) approach to antibody labeling which involves illumination of both the antibody and oYo-Link reagents with non-damaging Black-Light. This results in the formation of a highly stable covalent bond between oYo-Link and the Fc-binding site of the antibody. Any label that is attached to oYo-Link will therefore also be bound to the antibody’s heavy chain.
This unique site-specific labeling technique overcomes many of the common challenges that researchers face when using conventional antibody labeling techniques, such as heterogeneous products, reduced antibody functionality, and batch-to-batch variability.
In addition, oYo-Link affords several other time and cost-saving benefits for scientists, such as the ability to label extremely small amounts of antibody, as well as eliminating the requirement to purify the antibody prior to labeling.
The collaboration will provide AlphaThera’s customers with access to a new premium range of oYo-Link products for use in fluorescence-based applications such as flow cytometry, FACS and ELISA. Columbia Biosciences will use oYo-Link® reagents to expand their conjugation service offering.
John Morseman, CEO and co-founder of Columbia Biosciences commented “We are excited to expand our antibody and protein labeling service offering to include oYo-link technology. It will allow our clients additional options in early-stage assay development and reagent selection. We look forward to working with the team at AlphaThera to add new intense fluorophores in the near future.”
Dr. Andrew Tsourkas, Co-Founder of AlphaThera, commented, “We are delighted to be working with Columbia Biosciences to expand our oYo-Link range. With the addition of APC and PE to our oYo-Link range, we are able to significantly broaden our customer base to include researchers working with popular fluorescence-based applications such as flow cytometry. We look forward to continuing this partnership and further developing the oYo-Link® SureLight® product line.”
