Anti-Bcl-x Antibody

Bcl-x (BCL2L1) is a member of the BCL-2 family of apoptosis regulators, and tracking its expression by western blot, immunohistochemistry, and ELISA is a routine approach in cell survival and cancer signaling studies. This rabbit polyclonal reagent from Antibodies.com targets both Bcl-xL and Bcl-xS isoforms and is supplied as an unconjugated 100 µl aliquot, ready for dilution into standard antibody buffers. It has been validated for reactivity against human, mouse, and rat samples, making it practical for translational workflows that compare tumor, neural, or immune tissue across species. Apply the antibody at optimized dilutions for immunoblotting of total cell lysates, IHC on formalin-fixed paraffin-embedded sections, or antigen-capture ELISA. Store refrigerated for short-term use; for longer-term storage, aliquot and freeze to preserve activity through repeated freeze-thaw cycles. The polyclonal format recognizes multiple epitopes on the target, which can improve signal when antigen abundance is low, and the unconjugated format lets the end user pair it with HRP, biotin, or fluorophore labels of their choosing.
