Mouse Beta-2-Microglobulin (b2M) ELISA Kit | b2M elisa kit

Mouse Beta-2-Microglobulin (b2M) ELISA Kit

Cat. Num. AAA2023512

• Reactivity: Mouse
• Synonyms: Beta-2-Microglobulin (b2M); Mouse Beta-2-Microglobulin (b2M) ELISA Kit; b2M elisa kit

• Reactivity: Mouse
• Specificity: This assay has high sensitivity and excellent specificity for detection of b2M. No significant cross-reactivity or interference between b2M and analogues was observed.
• Sequence Length: 119

• Samples: Mouse serum, plasma, urine and other biological fluids
• Assay Type: Competitive
• Detection Range: 123.5-10,000pg/mL
• Sensitivity: The minimum detectable dose of b2M is typically less than 55.2pg/mL. The sensitivity of this assay, or Lower Limit of Detection (LLD) was defined as the lowest protein concentration that could be differentiated from zero. It was determined by subtracting two standard deviations to the mean optical density value of twenty zero standard replicates and calculating the corresponding concentration.
• Intra-assay Precision: Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level b2M were tested 20 times on one plate, respectively. Intra-Assay: CV<10%
• Inter-assay Precision: Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level b2M were tested on 3 different plates, 8 replicates in each plate. CV(%) = SD/meanX100. Inter-Assay: CV<12%
• Intended Uses: The kit is a competitive inhibition enzyme immunoassay technique for the in vitro quantitative measurement of b2M in mouse serum, plasma, urine and other biological fluids.
• Preparation and Storage: 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.

Principle of the assay: This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to b2M has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled b2M and unlabeled b2M (Standards or samples) with the pre-coated antibody specific to b2M. After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of b2M in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of b2M in the sample.

NCBI Description

This gene encodes a serum protein found in association with the major histocompatibility complex (MHC) class I heavy chain on the surface of nearly all nucleated cells. The protein has a predominantly beta-pleated sheet structure that can form amyloid fibrils in some pathological conditions. The encoded antimicrobial protein displays antibacterial activity in amniotic fluid. A mutation in this gene has been shown to result in hypercatabolic hypoproteinemia.[provided by RefSeq, Aug 2014]

Uniprot Description

B2M: Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system. Heterodimer of an alpha chain and a beta chain. Beta-2- microglobulin is the beta-chain of major histocompatibility complex class I molecules. Polymers of beta 2-microglobulin can be found in tissues from patients on long-term hemodialysis. Belongs to the beta-2-microglobulin family.
