Anti-Cotinine-4 Antibody

From Antibodies.com, this rabbit polyclonal reagent is supplied through the AFMS distribution network at Nordic Biosite as a primary antibody targeting the Cotinine-4 immunogen (Cotinine-4-BgG conjugate). Each vial delivers 1 mg of an unconjugated IgG fraction, Protein A purified from rabbit serum and presented in 10 mM Phosphate Buffered Saline at pH 7.0. The polyclonal antibody is validated for ELISA workflows with lateral flow as a secondary application, and it specifically recognizes the Cotinine-4 target with no reported cross-reactivity to other protein-conjugated cotinine positions. The product is intended strictly for research use only, is not approved for diagnostic or therapeutic applications, and should be stored short term at +2 to +8 °C for up to two weeks, or long term at –20 °C, with repeated freeze-thaw cycles avoided to preserve antibody activity. Conjugate status is unconjugated, giving laboratories full flexibility for downstream labeling or direct use in immunoassays that require clean primary detection.
