آنتی بادی مونوکلونال فلوسایتومتری IgA2- PerCP-Cyanine5.5 ، کلون SAA2

Name: Flow Cytometry Antibody IgA2-PerCP-Cyanine5.5, Clone SAA2

Antibody IgA2-PerCP-Cyanine5.5 is designed for flow cytometry use as a direct immunofluorescence reagent in the identification and enumeration of IgA2 expressing cells. IgA2-PerCP-Cyanine5.5 reacts with the Fc portion of the heavy chain of human IgA2.

In humans, 85–90% of IgA antibodies are found in body secretions such us saliva, tears, breast milk; gastrointestinal mucous membranes, urogenital and respiratory tracts and prostatic fluid, among others. The remaining fraction of 10–15% of IgA antibodies is found in blood, produced by B cells in the lymph nodes, bone marrow, and spleen. Two subclasses of human serum IgA exist. IgA1 tends to be monomeric and is present at a fivefold higher concentration than IgA2. Soluble IgA2 tends to be present more often in polymeric forms.

CYT-IGA2C2 should be used with BulkLysis^TM (CYT-BL) buffer that allows you to stain a great number of cells and analyze low frequency subsets, as IgA2+ memory B cells and plasma cells. If another lysing protocol is used, two pre-staining washing steps using PBS+1% (m/v) BSA + 0,09% (m/v) sodium azide must be performed.
