|Product name||Human Intrinsic factor IgG antibody ELISA Kit|
|Applications notes||This Human Intrinsic factor IgG antibody ELISA Kit employs the competitive enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with an antibody specific to IgG. Standards or samples are then added to the appropriate microtiter plate wells with a Horseradish Peroxidase (HRP)-conjugated IgG and incubated. The competitive inhibition reaction is launched between with HRP labeled IgG and unlabeled IgG with the antibody. A substrate solution is added to the wells and the color develops in opposite to the amount of IgG in the sample. The color development is stopped and the intensity of the color is measured.|
|SampleType||Cell culture supernatants, Other biological fluids, Plasma, Serum|
|Assay type||Sandwich ELISA (quantitative)|
|Assay duration||Multiple steps standard sandwich ELISA assay with a working time of 3-5 hours. It depends on the experience of the operation person.|

|Usage notes||• Do not mix components from different kit lots or use reagents beyond the kit expiration date.
• Allow all reagents to warm to room temperature for at least 30 minutes before opening.
• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.
• Unused wells must be kept desiccated at 4 °C in the sealed bag provided.
• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.
• It is recommended that all samples and standards be assayed in duplicate or triplicate.
|Storage instructions||The unopened kit should be stored at 2 - 8°C. After opening, please store refer to protocols.|

|Background||Intrinsic factor is a glycoprotein produced by the parietal cells of the stomach. It is necessary for the absorption of vitamin B12 later on in the terminal ileum.Upon entry into the stomach, vitamin B12 becomes bound to haptocorrin (R factor), a glycoprotein. The resulting complex enters the duodenum, where pancreatic enzymes digest haptocorrin. In the less acidic environment of the small intestine, B12 can then bind to intrinsic factor. This new complex travels to the ileum, where special epithelial cells endocytose them. Inside the cell, B12 dissociate once again and bind to another protein, transcobalamin II. The new complex can exit the epithelial cells to enter the liver.|
