• Reactivity: Human
• Specificity: This assay has high sensitivity and excellent specificity for detection of Lymphocyte Activation Gene 3 (LAG3).; No significant cross-reactivity or interference between Lymphocyte Activation Gene 3 (LAG3) and analogues was observed.
• Sequence Length: 525

• Assay Type: Double-antibody Sandwich
• Samples: Tissue homogenates, Cell lysates and Other Biological Fluids
• Detection Range: 0.156-10ng/mL
• Sensitivity: < 0.056ng/mL
• Application: Enzyme-linked immunosorbent assay for Antigen Detection.
• Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Lymphocyte Activation Gene 3 (LAG3) were tested 20 times on one plate, respectively.
• Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Lymphocyte Activation Gene 3 (LAG3) were tested on 3 different plates, 8 replicates in each plate.
• CV(%) =: SD/meanX100
• Intra-Assay: CV<10%
• Inter-Assay: CV<12%
• 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.

Related Product Information for LAG3 elisa kit

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 Lymphocyte Activation Gene 3 (LAG3). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Lymphocyte Activation Gene 3 (LAG3). 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 Lymphocyte Activation Gene 3 (LAG3), 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 Lymphocyte Activation Gene 3 (LAG3) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
