Human VPREB3 ELISA Kit (HUFI05722)

This Assay Genie Human VPREB3 ELISA Kit provides quantitative measurement of Pre-B Lymphocyte Protein 3, a small surrogate light chain component that pairs with the immunoglobulin heavy chain during early B-cell maturation in bone marrow. The protein is critical for pre-B cell receptor assembly and signaling, influencing the selection of functional B-cell precursors.

Intended for research use only, the kit supports investigations in B-cell development, common variable immunodeficiency (CVID), and B-cell leukemia biology. The capture antibody is human-specific with no significant cross-reactivity with rodent VPREB3 orthologs. Store reconstituted reagents at -20 degrees C in single-use aliquots; protect from light to preserve substrate activity. The microplate and reagents are supplied as a complete kit with all buffers, standards, and detection antibody included.
