Anti-Trypsin-1 (M109) Antibody

Raised in rabbit as a polyclonal reagent specific for human Trypsin-1, this unconjugated primary antibody is supplied by Antibodies.com in a 50 µl vial at 1 mg/ml, formulated in phosphate buffered saline with 0.05% sodium azide at approximately pH 7.2. The M109 designation refers to a defined epitope used during immunisation, and the antibody is validated for immunohistochemistry on human tissue sections, where it is applied to formalin-fixed paraffin-embedded samples to localise trypsinogen expression in pancreatic acinar cells. The unconjugated format allows researchers to pair the reagent with their own HRP, biotin, or fluorophore secondary detection systems, supporting chromogenic DAB staining as well as immunofluorescence workflows. The 50 µl pack size supports multiple staining runs on serial sections, and the liquid formulation in PBS with 0.05% sodium azide minimises background while preserving reagent stability during routine handling. For research use only, not for diagnostic procedures.
