Anti-Hexim1 Antibody

The HEXIM1 protein, a P-TEFb-binding transcription regulator involved in RNA polymerase II pausing, can be detected across immunoblotting, immunohistochemistry, and immunofluorescence workflows with this polyclonal reagent raised in rabbit. Supplied by Antibodies.com as a 50 µL aliquot of affinity-purified IgG at 1 mg/mL in PBS with 0.1% Sodium Azide and 50% glycerol, the antibody is unconjugated and ready for direct labeling or secondary detection chemistries. It cross-reacts with HEXIM1 orthologues from human, mouse, and rat samples, supporting comparative studies in cardiac hypertrophy, estrogen receptor signaling, and HIV transcriptional regulation research, where P-TEFb sequestration by HEXIM1 is a key mechanistic axis. Each vial is intended for research use only and should be stored at -20°C with protection from light; small working aliquots limit repeated freeze-thaw cycles and preserve batch-to-batch activity for western blot, IHC, and IF applications.
