| Product name | Human Macrophage scavenger receptor types I and II (MSR1) ELISA Kit |
| Reactivity | Human |
| Applications | ELISA |
| Applications notes | This Human Macrophage scavenger receptor types I and II (MSR1) ELISA Kit employs a two-site sandwich ELISA to quantitate MSR1 in samples. An antibody specific for MSR1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyMSR1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for MSR1 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 MSR1 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 | MSR1 encodes the class A macrophage scavenger receptors, which include three different types (1, 2, 3) generated by alternative splicing of this gene. These receptors or isoforms are macrophage-specific trimeric integral membrane glycoproteins and have been implicated in many macrophage-associated physiological and pathological processes including atherosclerosis, Alzheimer's disease, and host defense. The isoforms type 1 and type 2 are functional receptors and are able to mediate the endocytosis of modified low density lipoproteins (LDLs). The isoform type 3 does not internalize modified LDL (acetyl-LDL) despite having the domain shown to mediate this function in the types 1 and 2 isoforms. It has an altered intracellular processing and is trapped within the endoplasmic reticulum, making it unable to perform endocytosis. The isoform type 3 can inhibit the function of isoforms type 1 and type 2 when co-expressed, indicating a dominant negative effect and suggesting a mechanism for regulation of scavenger receptor activity in macrophages. |

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.
