Anti-SPARC Antibody

For researchers probing matricellular signaling in tissue remodeling and tumor microenvironment studies, this affinity-purified reagent from Antibodies.com delivers reliable detection of SPARC (Secreted Protein Acidic and Rich in Cysteine), also known as osteonectin, BM-40, or basement-membrane protein 40. Supplied as a 50 µl aliquot of an unconjugated rabbit polyclonal antiserum at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, the antibody is validated for Western Blot (WB) applications and cross-reacts with Human, Mouse, and Rat samples, making it well suited for comparative studies across standard laboratory models. The polyclonal format ensures broad epitope coverage, and the IgG isotype (rabbit host) provides flexibility for downstream detection with the wide range of anti-rabbit secondary reagents available from Antibodies.com. Routine storage at -20 °C, with avoidance of repeated freeze-thaw cycles, preserves the affinity-purified preparation (purity >95% by SDS-PAGE). Intended for research use only, this primary antibody is an economical choice for labs profiling SPARC expression without sacrificing specificity.
