Anti-CST2 Antibody

CST2 (Cystatin SA) is a secreted type 2 cysteine protease inhibitor expressed in human saliva, tears, and seminal fluid. This unconjugated rabbit polyclonal antibody from Antibodies.com targets CST2 for use in Western blot, immunohistochemistry, and immunofluorescence workflows. The reagent is supplied at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol as a stabilizing agent, and reacts specifically with human CST2. CST2 inhibits lysosomal cathepsins and has been investigated as a biomarker in gastric and breast cancer studies. Researchers use this antibody to characterize CST2 expression patterns in tissue sections and cell lysates. Storage recommendations include aliquoting to avoid repeated freeze-thaw cycles, and the product ships in a 100 µl vial for standard laboratory use.
