General description

IgA antibody is secretory antibody and is present abundantly in mucous linings of gastrointestinal, respiratory and genitourinary tracts, tears and saliva. Thus secretory IgA contributes to the humoral defense mechanism against the pathogens on mucosal surfaces
Anti-Human IgA (α-chain specific)-FITC antibody is specific for α chain of human IgA. Goat Anti-Human IgA is conjugated to Fluorescein Isothiocyanate (FITC), Isomer I.

Immunogen

Purified human IgA

Application

Anti-Human IgA (α-chain specific)-FITC antibody may be used for direct immunofluorescence at a working antibody dilution of 1:16 to 1:32. A dilution of 1:100 was used for immunohistochemistry of cryosections of human sural nerves.

Packaging

1, 2 mL in glass bottle

Physical form

Solution in 0.01 M phosphate buffered saline pH 7.4, containing 1% BSA and 15 mM sodium azide

Quantitative immunocytochemical analysis of complement proteins (CP) was performed on sural nerve biopsies from 15 patients with diabetic neuropathy (DN) and 18 nondiabetic patients with other forms of chronic neuropathy (ON). The mean age of the patients and the pathological...

Cholesterol crystals (CC) are abundant in atherosclerotic plaques and promote inflammatory responses via the complement system and inflammasome activation. Cyclic oligosaccharide 2-hydroxypropyl-β-cyclodextrin (BCD) is a compound that solubilizes lipophilic substances. Recently we have shown that BCD has an anti-inflammatory effect...

Short-chain fatty acids (SCFAs) butyrate and propionate are metabolites from dietary fiber's fermentation by gut microbiota that can affect differentiation or functions of T cells, macrophages and dendritic cells. We show here that at low doses these SCFAs directly impact B...

Class-switch DNA recombination (CSR) and somatic hypermutation (SHM), which require activation-induced cytidine deaminase (AID), and plasma cell differentiation, which requires B lymphocyte-induced maturation protein-1 (Blimp-1), are critical for the generation of class-switched and hypermutated (mature) Ab and autoantibody responses. We...

Intestinal handling of dietary proteins usually prevents local inflammatory and immune responses and promotes oral tolerance. However, in ~ 1% of the world population, gluten proteins from wheat and related cereals trigger an HLA DQ2/8-restricted TH1 immune and antibody response leading...
