Anti-GAP43 (phospho S41) Antibody - Identical to Abcam (ab194929)

A rabbit polyclonal IgG antibody raised against the phospho-S41 epitope of GAP43 (Growth Associated Protein 43), supplied by Antibodies.com as 50 µl of unconjugated reagent for immunofluorescence workflows. GAP43 is a membrane-associated phosphoprotein highly expressed in developing and regenerating neurons, and phosphorylation at Ser41 is a PKC-dependent modification linked to synaptic plasticity, neurite extension, and axon outgrowth. This reagent selectively recognizes the phosphorylated form of the target in human, mouse, and rat samples, supporting neuroscience research into nerve injury models, activity-dependent remodeling, and developmental neurobiology. Host species is Rabbit with Polyclonal clonality, and the unconjugated format allows flexible pairing with user-selected secondary reagents for IF imaging of fixed cells and tissue sections. For reliable results, store refrigerated and minimize freeze-thaw cycles to preserve phospho-epitope reactivity across repeated experiments.
