Introduction of Chromatography Assay
Affinity-based chromatography is a powerful and specific separation method used for bioactive compound isolation and purification employing the binding affinity between immune complexes. Specific monoclonal antibodies or patient immunoglobulin have been used to capture human or mouse tumor tissue-derived antigens, HLA-restricted tumor-specific antigens, and neoantigens. Following the capture process, the proteins bound to the chromatography are eluted and evaluated by various other methods.

Receptor-ligand-based Affinity Chromatography
Biotinylated monoclonal antibodies are incubated with the antigen protein mixture, and the formed antigen-antibody complex is purified by an avidin column. Finally, the bound antigens are separated using a proper elution buffer.

Highlights
High Specificity
Our chromatography-based method enables the precise isolation of B cells with the highest affinity for your target antigen. This ensures that you obtain the most specific and potent antibody candidates from your initial sample.
Large-scale
The assay platform is built to handle a large volume of B cells from a single sample. This allows for the rapid screening of a vast antibody repertoire, increasing the probability of discovering rare, high-value clones.
High Efficiency
By directly isolating antigen-specific B cells, our streamlined workflow bypasses time-consuming and inefficient steps like hybridoma fusion, dramatically accelerating the timeline from sample to gene sequence.
Cost-effective Price
Our efficient, high-throughput process significantly reduces labor and material costs compared to traditional methods. This allows you to achieve a higher success rate with a lower overall investment.

Customer Reviews
Exceptional Speed and Efficiency
Using Creative Biolabs' B cell-based chromatography assay in our research has significantly improved the speed of our lead antibody identification. The process is remarkably streamlined, saving us months of development time. - Da Rs.
Confidence in Candidate Quality
The assay provided highly specific B cells, eliminating months of frustrating post-screening work and giving us confidence in our candidates from day one. We received a panel of clones that were ready for immediate downstream work. - Ae Mn.
FAQs
What are the key advantages of this method for discovering antibodies from immunized animals?
The primary advantage is speed and specificity. Our assay significantly compresses the timeline from immunization to candidate identification. By directly selecting for antigen-specific B cells, we ensure that the candidates you receive have already undergone natural affinity maturation.
Can this assay be used to identify antibody fragments or scFv?
Yes. We can isolate B cells that produce a variety of antibody formats, including fragments. As demonstrated in published research, specialized affinity ligands such as Protein L can be effectively used for purifying these fragments, and our upstream assay is perfectly compatible with these downstream purification protocols.
