Background
Helicobacter pylori (H. pylori) is detectable in nearly 100% of adult patients with duodenal ulcer and about 80% of patients with gastric ulcer. An association between H. pylori and gastric cancer is confirmed. In developing countries, where most children become infected by the age of 10, gastric cancer rates are very high. In the USA and other developed countries, standards of hygiene and the increasing socioeconomic status of the population have reduced the incidence of infection, and in parallel, the rates of peptic ulcers and gastric cancer have declined. There is excellent correlation between the clinical presentation of gastritis, the presence of H. pylori in the stomach and elevated serum H. pylori IgG and IgA antibodies. ELISA sensitivity and specificity are 90%, and the predictive value of a negative result for is very high. H. pylori IgG and/or IgA antibodies falls significantly after successful antibacterial therapy. Eradication of H. pylori is associated with a significant reduction in duodenal ulcer recurrence. pylori strains are classified into two broad groups - those that express both VacA and CagA (type I) and those that produce neither (type II). Type I strains are predominate in patients with ulcers and cancer. Up to 50% of adults is infected with H. pylori, but most of them are asymptotic and will not develop ulcer. The reason is they are infected with type II. 80-100% of patients with duodenal ulcer disease produce CagA antibodies against a 128 kd antigen compared with 60-63% of H. pylori-infected persons with gastritis only, indicating that serologic responses to the 128 kd protein are more prevalent among H. pylori-infected persons with duodenal ulcers than infected persons without peptic ulceration. In H. pylori-infected patients who develop gastric cancer, serum IgG against CagA 94% sensitive and 93% specific, indicating that detection of antibodies to CagA is useful marker for diagnosis of duodenal ulcer and gastric cancer.

About
Immunoglobulin gamma, IgG, mouse monoclonal H&L chain clones or rabbit, goat polyclonal antibodies have 4 parts. There are 2 heavy chains, 2 light chains. The IgG antibody has 2 antigen binding sites. They represent 70% or more of serum antibodies. This antibody can be antigen purified or protein A or G purified. For storage sodium azide is added or you can call us to request azide free antibody preparations. These will need colder storage temperatures.

Technique
ELISA kit, ELISA, IgG, ELISAs Enzyme-linked immunosorbent assay 90320007 SNOMED code are used by the medical researcher for detection of human, mouse, … proteins are supplied in coated 96 well plates to be stored at +4°C. ELISA test kits can be sandwich ELISA. In sandwich ELISAS Enzyme-linked immunosorbent assay 9we use captor and detector antibodies. In single antibody ELISAs the antigen is coated and only a detector antibody is used. Traditional competition antigen ELISAs are coated with a captor antibody and a competitive antigen is labelled with the chromogen. In this case the ratio on your graph will be inverse proportional with the antigen present in your sample. A sign detected by the Colorimetric detection OD optical density absorbance at 450 nm between 0 and 4 with an ELISA reader for 450 nm absortion.

Concept
Scope note:
An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
