Rabbit anti-Human Immunoglobulin G4 Antibody | anti-IgG4 antibody
Polyclonal Antibody to Immunoglobulin G4 (IgG4)
Immunohistochemistry: 5-20ug/mL
Immunocytochemistry: 5-20ug/mL
Optimal working dilutions must be determined by end user.
Avoid repeated freeze/thaw cycles.
Store at 4 degree C for frequent use.
Aliquot and store at -20 degree C for 24 months.
Stability Test:
thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37 degree C for 48h, and no obvious degradation and precipitation were observed. The loss rate is less than 5% within the expiration date under appropriate storage condition.

NCBI and Uniprot Product Information
Uniprot Description
IGHG4: Constant region of immunoglobulin heavy chains. Immunoglobulins, also known as antibodies, are membrane-bound or secreted glycoproteins produced by B lymphocytes. In the recognition phase of humoral immunity, the membrane-bound immunoglobulins serve as receptors which, upon binding of a specific antigen, trigger the clonal expansion and differentiation of B lymphocytes into immunoglobulins-secreting plasma cells. Secreted immunoglobulins mediate the effector phase of humoral immunity, which results in the elimination of bound antigens (PubMed:22158414, PubMed:20176268). The antigen binding site is formed by the variable domain of one heavy chain, together with that of its associated light chain. Thus, each immunoglobulin has two antigen binding sites with remarkable affinity for a particular antigen. The variable domains are assembled by a process called V-(D)-J rearrangement and can then be subjected to somatic hypermutations which, after exposure to antigen and selection, allow affinity maturation for a particular antigen (PubMed:17576170, PubMed:20176268). {ECO:0000303|PubMed:17576170, ECO:0000303|PubMed:20176268, ECO:0000303|PubMed:22158414}. Immunoglobulins are composed of two identical heavy chains and two identical light chains; disulfide-linked. {ECO:0000303|PubMed:20176268}

Product Notes
The IgG4 ighg4 (Catalog #AAA2028130) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The Polyclonal Antibody to Immunoglobulin G4 (IgG4) reacts with Human and may cross-react with other species as described in the data sheet. AAA Biotech's Immunoglobulin G4 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), Immunocytochemistry (ICC), Immunohistochemistry (IHC), Immunoprecipitation (IP). Western blotting: 0.5-2ug/mL Immunohistochemistry: 5-20ug/mL Immunocytochemistry: 5-20ug/mL Optimal working dilutions must be determined by end user. Researchers should empirically determine the suitability of the IgG4 ighg4 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Immunoglobulin G4, Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
