Anti-CTLA4 Antibody

This rabbit polyclonal primary antibody from Antibodies.com targets human CTLA4, a key immune checkpoint receptor expressed on regulatory and activated T cells. Supplied at 1 mg/ml in phosphate buffered saline (PBS) with 0.05% sodium azide at approximately pH 7.2, the unconjugated reagent is validated for western blot (WB) and immunohistochemistry (IHC) workflows. Each vial contains 50 µl of antibody, and the polyclonal formulation enables recognition of multiple epitopes on the CTLA4 protein, supporting reproducible detection across a range of sample preparations. Researchers apply this reagent to investigate immune checkpoint regulation, autoimmune disease mechanisms, and tumor immunology studies where CTLA4 expression profiling is required. The host species is rabbit, and the antibody shows reactivity with human samples, making it suitable for translational research into T cell inhibition pathways and checkpoint blockade biology.
