How big is GAPDH?
GAPDH molecule is a homotetramer composed of 36 kDa subunits. Thus the molecular weight for the whole molecule is 144 kDa.
Why do we use GAPDH in Western blot?
GAPDH antibody, is usually used as a loading control antibody for Western Blot to normalize the levels of protein detected by confirming that protein loading is the same across the gel.
What is anti GAPDH?
Anti-GAPDH monoclonal antibodies developed by HyTest, especially the well characterized MAb 6C5, are suitable for GAPDH immunodetection in Western blotting, sandwich immunoassays and immunocytochemical applications.
What does GAPDH do in glycolysis?
Glyceraldehyde 3-phosphate dehydrogenase (GAPDH) is an enzyme involved in breaking down glucose to obtain energy. More specifically, in eukaryotes, this enzyme catalyzes the sixth step in glycolysis, converting glyceraldehyde 3-phosphate to D-glycerate 1,3-bisphosphate (1,3-BPG).
Why is GAPDH used in PCR?
As one of the most common reference genes, GAPDH is often used to normalize the gene expression data, being used as an endogenous control in the quantitative analysis of RT-PCR, since in some experimental systems, its expression is very constant (Edwards and Denhardt 1985; Winer et al. 1999).
Is GAPDH a good control?
GAPDH is a reliable internal control only for ischemic myocardium of Rhesus monkey.
Where is GAPDH?
In addition to the cytoplasm where majority of GAPDH is located under the basal condition, GAPDH is also found in the particulate fractions, such as the nucleus, the mitochondria, and the small vesicular fractions. When cells are exposed to various stressors, dynamic subcellular re-distribution of GAPDH occurs.
What type of protein is GAPDH?
GAPDH is a homo tetramer containing four identical 37 kDa subunits. Localized in chromosome 12, human GAPDH gene transcribes single mRNA species, consequently producing a subunit that comprises a polypeptide chain of 335 amino acids7,8.
Is GAPDH part of glycolysis?
GAPDH is the sixth enzyme of glycolysis, whereas CytOx is the fourth complex of the mitochondrial oxidative phosphorylation system. Both GAPDH and CytOx are highly regulated under normal energy metabolic conditions, but both of these enzymes are highly deregulated in the presence of oxidative stress.
What part of the antibody combines with the antigen?
The part of the antigen which combines with the antibody is called epitope or antigenic determinates. An antigen may contain 10 to 50 antigenic determinants. Some time it may go up to 200. The part of the antibody which combines with the antigen is called paratope or antigen binding site.
How are monoclonal antibody produced?
Monoclonal antibodies are produced by injecting an antigen into a host animal to initiate a humoral immune response. In most procedures, spleen cells from these hosts are fused in vitro with cultured malignant myeloma cells. Unique cell clones are isolated and those that survive the fusion step are known as hybridomas.
What is anti – thyroid antibody?
Thyroid autoantibodies are antibodies that develop when a person’s immune system mistakenly targets components of the thyroid gland or thyroid proteins, leading to chronic inflammation of the thyroid (thyroiditis), tissue damage, and/or disruption of thyroid function.
What is anti cardiolipin antibody?
Cardiolipin antibodies are the most common antiphospholipid antibody, a group of autoantibodies associated with excessive clotting and autoimmune diseases, such as lupus. They are frequently detected with other antiphospholipid antibodies, such as lupus anticoagulant and anti-beta-2 glycoprotein 1.
