Gamma-synuclein (originally known as a breast cancer specific gene product, BCSG1) is an acidic neuronal protein of 127 amino acids. The protein coding region of gamma-synuclein was amplified by RT-PCR and cloned into an E. coli expression vector. Gamma-synuclein was overexpressed in E. coli and purified to apparent homogeneity by taking advantage of the thermosolubility of the protein and by using conventional column chromatography techniques. Synonyms: Monoclonal SNCG antibody, Anti-SNCG antibody, BCSG1 antibody, PERSYN antibody, PRSN antibody, Persyn antibody, Breast cancer-specific gene 1 protein antibody, Synoretin antibody, SR antibody, gamma-synuclein antibody, gamma synuclein antibody.
