Human EFCAB4B ELISA Kit (HUFI04503)

This Assay Genie ELISA Kit enables quantitative measurement of human EFCAB4B (EF-hand calcium-binding domain 4B), a calcium-signaling protein implicated in store-operated calcium entry and lymphocyte activation. The immunoassay is supplied as a complete kit with pre-coated microplate wells, capture antibody, detection antibody, recombinant standard, and buffer reagents sufficient for 96 determinations. Researchers apply the assay for in vitro studies of EFCAB4B expression in serum or plasma specimens from donors, using 50 μL of sample per well, supporting investigations of T-cell receptor signaling pathways, immune-cell calcium homeostasis, and CRAC channel regulation. Store unopened components refrigerated at 4 degrees C; reconstituted standards and antibodies should be frozen at -20 degrees C in single-use aliquots to limit freeze-thaw cycles. For research use only.
