| Product name | Human Shadow of prion protein (SPRN) ELISA Kit |
| Reactivity | Human |
| Applications | ELISA |
| Applications notes | This Human Shadow of prion protein (SPRN) ELISA Kit employs a two-site sandwich ELISA to quantitate SPRN in samples. An antibody specific for SPRN has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anySPRN present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for SPRN is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of SPRN 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 | SPRN expression in human, rat, and mouse brain. The deduced human protein contains 151 amino acids. The mammalian proteins share 81 to 95% sequence identity. Alignment of all fish and mammalian Sho proteins showed that all have an N-terminal peptide sequence with an endoplasmic reticulum targeting signal for extracellular transport, a basic RG-rich region, a hydrophobic stretch in the middle of the protein that contains the same unusual composition of small aliphatic residues (GAV) as PrP and PrP-like proteins, and a C-terminal region with a putative N-glycosylation site and a possible GPI anchor site (Premzl et al., 2003, 2004). Database searches revealed that SPRN is expressed in mouse and rat embryo, brain, and retina, in human hippocampus, and in zebrafish embryo and retina. |

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.
