Human SDF-1 beta PharmaGenie ELISA Kit (SBRS1063)

Built around the CXC chemokine CXCL12, this ELISA-format quantitative immunoassay supports research into stromal-derived signaling that governs hematopoietic stem and progenitor cell homing to bone marrow niches, embryonic cardiac and neural development, and lymphocyte trafficking during inflammatory responses. The SDF-1 beta splice variant differs from SDF-1 alpha by a short C-terminal extension that alters proteolytic processing, receptor-binding kinetics, and association with heparan sulfate proteoglycans on cell surfaces, so isoform-distinguishing quantitation is increasingly used in oncology, regenerative medicine, and immunology workflows. The kit, supplied by Assay Genie, is intended for human sample measurement in research use only settings and accepts cell culture supernatant starting material along with plasma- and serum-derived preparations. An absorbance-based readout integrates with standard microplate reader workflows for in vitro studies of the SDF-1/CXCR4 axis in tumor microenvironment signaling, hematopoietic stem cell mobilization, and immune cell recruitment studies.
