This assay has high sensitivity and excellent specificity for detection of Macrophage Scavenger Receptor 1 (MSR1). No significant cross-reactivity or interference between Macrophage Scavenger Receptor 1 (MSR1) and analogues was observed.

For unopened kit: All the reagents should be kept according to the labels on vials. The Standard, Detection Reagent A, Detection Reagent B and the 96-well strip plate should be stored at -20 degree C upon receipt while the others should be at 4 degree C. For opened kit: When the kit is opened, the remaining reagents still need to be stored according to the above storage condition. Besides, please return the unused wells to the foil pouch containing the desiccant pack, and reseal along entire edge of zip-seal. The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

Samples: Tissue homogenates, Cell lysates and other biological fluids. Assay Type: Sandwich. Detection Range: 0.313-20ng/mL. Sensitivity: Typically less than 0.122ng/mL.

Precision: Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Macrophage Scavenger Receptor 1 (MSR1) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Macrophage Scavenger Receptor 1 (MSR1) were tested on 3 different plates, 8 replicates in each plate. CV(%) = SD/meanX100 . Intra-Assay: CV<10% . Inter-Assay: CV<12% . Assay Procedure Summary: 1. Prepare all reagents, samples and standards;. 2. Add 100uL standard or sample to each well. Incubate 2 hours at 37 degree C;. 3. Aspirate and add 100uL prepared Detection Reagent A. Incubate 1 hour at 37 degree C;. 4. Aspirate and wash 3 times;. 5. Add 100uL prepared Detection Reagent B. Incubate 30 minutes at 37 degree C;. 6. Aspirate and wash 5 times;. 7. Add 90uL Substrate Solution. Incubate 15-25 minutes at 37 degree C;. 8. Add 50uL Stop Solution. Read at 450nm immediately.

Principle of the Assay: The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Macrophage Scavenger Receptor 1 (MSR1). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Macrophage Scavenger Receptor 1 (MSR1). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Macrophage Scavenger Receptor 1 (MSR1), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm 10nm. The concentration of Macrophage Scavenger Receptor 1 (MSR1) in the samples is then determined by comparing the O.D. of the samples to the standard curve.

This gene 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.

MSR1: Membrane glycoproteins implicated in the pathologic deposition of cholesterol in arterial walls during atherogenesis. Two types of receptor subunits exist. These receptors mediate the endocytosis of a diverse group of macromolecules, including modified low density lipoproteins (LDL). Isoform III does not internalize actetylated LDL. Defects in MSR1 may be a cause of prostate cancer (PC). A malignancy originating in tissues of the prostate. Most prostate cancers are adenocarcinomas that develop in the acini of the prostatic ducts. Other rare histopathologic types of prostate cancer that occur in approximately 5% of patients include small cell carcinoma, mucinous carcinoma, prostatic ductal carcinoma, transitional cell carcinoma, squamous cell carcinoma, basal cell carcinoma, adenoid cystic carcinoma (basaloid), signet- ring cell carcinoma and neuroendocrine carcinoma. MSR1 variants may play a role in susceptibility to prostate cancer. MSR1 variants have been found in individuals with prostate cancer and co-segregate with the disease in some families. Defects in MSR1 may be a cause of Barrett esophagus (BE). A condition characterized by a metaplastic change in which normal esophageal squamous epithelium is replaced by a columnar and intestinal-type epithelium. Patients with Barrett esophagus have an increased risk of esophageal adenocarcinoma. The main cause of Barrett esophagus is gastroesophageal reflux. The retrograde movement of acid and bile salts from the stomach into the esophagus causes prolonged injury to the esophageal epithelium and induces chronic esophagitis, which in turn is believed to trigger the pathologic changes. Genetic variants in MSR1 have been found in individuals with Barrett esophagus and are thought to contribute to disease susceptibility. 3 isoforms of the human protein are produced by alternative splicing. Protein type: Membrane protein, integral. Chromosomal Location of Human Ortholog: 8p22. Cellular Component: collagen; integral to plasma membrane; plasma membrane; cytosol. Molecular Function: protein binding; low-density lipoprotein binding; scavenger receptor activity. Biological Process: receptor-mediated endocytosis; cholesterol transport; lipoprotein transport. Disease: Prostate Cancer; Barrett Esophagus
