英文名称:
EasyPro Mouse IgM(Immunoglobulin M) ELISA Kit
样品类型:
Serum, Plasma, Tissue homogenate and Other biological samples;Sample Volume=50uL
研究领域:
intracellular signal transduction and neuron's development and viability.
测试原理:
This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to IgM. Samples (or Standards) and and Horseradish Peroxidase (HRP) linked antibody specific for IgM are added to the micro ELISA plate wells. IgM in samples (or standards) combines with the coated antibody and HRP linked detection antibody special to IgM. Excess conjugate and unbound sample or standard are washed from the plate. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm. The OD value is proportional to the concentration of IgM. You can calculate the concentration of IgM in the samples by comparing the OD of the samples to the standard curve.
技术数据
As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, washing technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data is provided below for reference only.

精密度
Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level were tested on 3 different plates, 20 replicates in each plate, respectively.
