Anti-PTMA Antibody [4G2]

Clone 4G2 is a mouse monoclonal IgG1 antibody that targets the human Prothymosin alpha (PTMA) protein, supplied by Antibodies.com as a 100 µg lyophilised preparation intended for research use only. Prothymosin alpha is a small, acidic nuclear polypeptide of approximately 12 kDa involved in chromatin remodeling, cell cycle progression, and the regulation of apoptosis, and it is widely used as a marker of proliferative activity in oncology and cell biology studies. The unconjugated format lets researchers pair this reagent with their own labelled secondary antibodies for Western blot or ELISA-based detection, making it adaptable across standard immunodetection workflows. The lyophilised pellet can be reconstituted in PBS or another suitable buffer, and the dried preparation is stable for long-term storage at refrigerated temperatures when handled according to standard laboratory practice. Investigators working on tumour biology, nuclear signalling, or proliferation in human cell models can apply this antibody to assess endogenous PTMA expression in lysates and tissue samples, or to confirm overexpression in transfected systems, supporting applications in cancer research, gene regulation studies, and basic biochemistry of the chromatin-associated proteome.
