Antigen background
Human IgA (immunoglobulin A) is a glycosylated protein of 160 kDa and is produced as a monomer or as a J chain linked dimer. Monomeric IgA constitutes 5-15 % of the serum immunoglobulins whereas dimeric IgA is localized to mucosa surfaces such as saliva, gastrointestinal secretion, bronchial fluids and milk. Mucosal IgA plays a major role in host defence by neutralising infectious agents at mucosal surfaces. The production is usually local and antigen specific IgA producing B cells can be found in regions under the lamina propria where they mature into dimeric IgA producing plasma cells. IgA deficiency is the most common immunodeficiency that may affect both serum and mucosal produced IgA.

Properties
If you buy Antibodies supplied by Bioss Primary Conjugated Antibodies they should be stored frozen at - 24°C for long term storage and for short term at + 5°C. This Bioss Primary Conjugated Antibodies Fluorescein isothiocyanate (FITC) antibody is currently after some BD antibodies the most commonly used fluorescent dye for FACS. When excited at 488 nanometers, FITC has a green emission that's usually collected at 530 nanometers, the FL1 detector of a FACSCalibur or FACScan. FITC has a high quantum yield (efficiency of energy transfer from absorption to emission fluorescence) and approximately half of the absorbed photons are emitted as fluorescent light. For fluorescent microscopy applications, the 1 FITC is seldom used as it photo bleaches rather quickly though in flow cytometry applications, its photo bleaching effects are not observed due to a very brief interaction at the laser intercept. Bioss Primary Conjugated Antibodies FITC is highly sensitive to pH extremes. Human proteins, cDNA and human recombinants are used in human reactive ELISA kits and to produce anti-human mono and polyclonal antibodies. Modern humans (Homo sapiens, primarily ssp. Homo sapiens sapiens). Depending on the epitopes used human ELISA kits can be cross reactive to many other species. Mainly analyzed are human serum, plasma, urine, saliva, human cell culture supernatants and biological samples. Immunoglobulin A (IgA, also referred to as sIgA) is an antibody that plays a critical role in immune function in the mucous membranes. More IgA is produced in mucosal linings than all other types of antibody combined. Examples are EMA, ACA ELISA test kits and for diagnostic detection the IgA of Anti-Beta-2 Glycoprotein 1; β2-Glycoprotein 1 Antibodies; Beta 2GP1 Ab, Beta-2 Glycoprotein 1 Antibodies IgG, IgM, and IgAs.

Description
Azide Free Serum for cell culture FBS fetal bovine serum. Filtered serum for sterility. The polyclonal serum contains no red or white blood cells or clotting factors; it is the blood plasma not including the fibrinogens. Serum includes all proteins and antibodies not used in blood clotting (coagulation) and all the electrolytes, antibodies, antigens, hormones, and any exogenous substances like drugs and microorganisms. Plasmas on request.
