Human IgA；来源于人初乳IgA；MDL number MFCD00164090 NACRES NA.46General description IgA antibody is secretory antibody and is present abundantly in mucous linings of gastrointestinal, respiratory and genitourinary tracts, tears, colostrum and saliva. Thus secretory IgA contributes to the humoral defense mechanism against the pathogens on mucosal surfaces[2] Human IgA is purified from pooled normal human colostrum by fractionation and ion-exchange fractionation. Application Purified IgA may be used as a reference antigen, standard, blocking agent or coating protein in a variety of immunoassays including ELISA, dot immunobinding, immunoblotting, immunodiffusion and immunoelectrophoresis. Other applications include starting materials for the preparation of immunogens and solidphase immunoadsorbents. IgA from human colostrum was used as a standard in ELISA (1 mg/ml)[1][3] and gel electrophoresis.[4] 包装 5, 25 mg in glass bottle Reconstitution Reconstitute with buffered saline (150 mM sodium chloride).
