There are many commercial antibodies with little information provided by their suppliers as to their reliability. Accordingly, commercial antibodies require proper validation before being used in scientific research. In this study, we validated several commercial antibodies, including anti-CSPα, SNAP25, tyrosine hydroxylase, ubiquitin, cleaved caspase 3, and pSer PKC motif. Anti-CSPα, SNAP25, and tyrosine hydroxylase antibodies could detect their endogenous target proteins with some degree of cross-reactivity. Furthermore, clear SNAP25 staining was observed with SNAP25 antibody. Antibodies directed against ubiquitin, cleaved caspase 3, and pSer PKC motif could detect poly-ubiquitination, apoptosis, and phosphorylation, respectively.
