| Product name | EliKine™ Human β-hCG ELISA Kit |
| Reactivity | Human |
| Applications | ELISA |
| Applications notes | EliKine™ Human β-hCG ELISA Kit employs a two-site sandwich ELISA to quantitate β-hCG in samples. An antibody specific for β-hCG has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any β-hCG present is bound by the immobilized antibody. After removing any unbound substances, a HRP conjugated antibody specific for β-hCG is added to the wells. Following a wash to remove any unbound enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of β-hCG bound in the initial step. The color development is stopped and the intensity of the color is measured. |

| 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. |
| Shipping | Gel pack with blue ice. |

| Background | Human chorionic gonadotropin (hCG) is a glycoprotein hormone produced by trophoblastic cells of the placenta beginning 10 to 12 days after conception. Maintenance of the fetus in the first trimester of pregnancy requires the production of hCG, which binds to the corpus luteum of the ovary which is stimulated to produce progesterone which in turn maintains the secretory endometrium. hCG is present only in trace amounts in non pregnant urine and sera. It rises sharply during pregnancy. HCG is composed of two non identical, non covalently linked polypeptide chains designated as the a and b subunits. The a subunit of HCG is nearly identical to that of thyroid stimulating hormone (TSH), follicle stimulating hormone (FSH) and luteinizing hormone (LH). A germ cell tumor which is positive for cytokeratin, placental alkaline phosphatase (PLAP) and HCG but negative for EMA and AFP is probably a choriocarcinoma. |

1.The species of antibody reactivity should be the sample species that can be matched normally after Abbkine R&D experts have passed strict scientific verification. If your sample is not within the range of reactivity, in order to improve the efficiency and results of your experiment, it is not suggested to try other species. Otherwise, it may lead to sample mismatch and affect the effect of your experiment.
2.Please aliquot the antibody received as soon as possible and store it at -20℃, avoid repeated freezing and thawing, and use it within one year.
