Product Information
KE00132 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The AFP ELISA kit is to be used to detect and quantify protein levels of endogenous AFP. The assay recognizes human AFP. An antibody specific for AFP has been pre-coated onto the microwells. The AFP protein in samples is captured by the coated antibody after incubation. Following extensive washing, another horseradish peroxidase(HRP)-conjugated antibody specific for AFP is added to detect the captured AFP protein. For signal development, followed by Tetramethyl-benzidine (TMB) reagent. Solution containing sulfuric acid is used to stop color development and the color intensity which is proportional to the quantity of bound protein is measurable at 450 nm with the correction wavelength set at 630 nm.

Background Information
AFP (alpha-fetoprotein) is a major plasma protein found in the fetus while plasma levels decrease rapidly after birth. AFP is one of the earliest markers of the hepatocyte lineage. High AFP concentrations have been correlated with tumor cell growth. Detection of AFP in plasma is important in diagnosis of hepatocellular carcinoma (HCC), stomach cancer and germ cell cancers. Altered levels of both fetal and maternal AFP have been associated with hypothyroidism, autoimmune disorders, and heart defects.

FAQ
1、I have limited sample diluent. How should I handle samples requiring high dilution factors?
Answer: We recommend performing a serial dilution. For example, if human serum requires a 1,000,000-fold dilution, you can use a three-step 100× dilution method as follows:
Step 1: Take 2 uL of human serum and add it to 198 uL of sample diluent, mix thoroughly to obtain a 100-fold diluted sample.
Step 2: Take 2 uL of the 100-fold diluted sample and add it to 198 uL of sample diluent, mix thoroughly to obtain a 10,000-fold diluted sample.
Step 3: Take 2 uL of the 10,000-fold diluted sample and add it to 198 uL of sample diluent, mix thoroughly to obtain a 1,000,000-fold diluted sample.
If further dilution is required, additional serial steps can be used. We do not recommend using any other solutions or water for dilution, except for the sample diluent we suggest. If your sample diluent is still insufficient, please contact our customer service for more sample diluent.
