Deionized or distilled water. 500 mL graduated cylinders. Test tubes for dilution.

Application Details

Application Notes: Before using Kit, spin tubes and bring down all components to bottom of tube. Duplicate well assay was recommended for both standard and sample testing.

Sample Volume: 100 μL

Plate: Pre-coated

Protocol: ELISA Kit is based on standard sandwich enzyme-linked immune-sorbent assay technology. An antibody has been precoated onto 96-well plates. Standards and test samples are added to the wells, a biotinylated detection antibody specific for target is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the target amount in sample captured in plate.

Assay Precision: Intra-Assay Precision (CV%): 3.2%, 5.6%, 7.5%

Target Details for PD-L1

Target: PD-L1 (CD274 (PD-L1))

Alternative Name: CD274

Background:

Background: Programmed death-ligand 1 (PD-L1) also known as cluster of differentiation 274 (CD274) or B7 homolog 1 (B7-H1) is a protein that in humans is encoded by the CD274 gene. Programmed death-ligand 1 (PD-L1) is a 40 kDa type 1 transmembrane protein that has been speculated to play a major role in suppressing the adaptive arm of immune systems during particular events such as pregnancy, tissue allografts, autoimmune disease and other disease states such as hepatitis. Normally the adaptive immune system reacts to antigens that are associated with immune system activation by exogenous or endogenous danger signals.
