Rat BH3 Interacting Domain Death Agonist (Bid) ELISA Kit

Beyond quantitative detection, this Assay Genie kit is frequently deployed in studies of death receptor signaling cascades, where full-length Bid is cleaved by caspase-8 into truncated tBid that translocates to the mitochondrial outer membrane to engage Bax and Bak. Researchers commonly apply it to hepatotoxicity models, chemotherapy-induced apoptosis screens, and TNF/Fas pathway investigations in rat primary hepatocytes, hepatic tissue, and neuronal cultures. For cell lysates, supplementing lysis buffer with protease inhibitors helps preserve intact Bid and prevents artifactual caspase-mediated truncation during sample handling. The biotin-streptavidin-HRP workflow delivers strong signal amplification, and standard curves generated from the included recombinant Bid allow accurate interpolation across the working range even with low-abundance samples such as brain or pancreatic tissue homogenates. Researchers measuring Bid cleavage products will benefit from aliquoting lysates immediately after collection and freezing them at -80 degrees C to preserve the pro-apoptotic fragment profile.
