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.

Target Details for ICOSLG

Target: ICOSLG (Inducible T-Cell Co-Stimulator Ligand (ICOSLG))

Alternative Name: ICOSLG

Background:

Background: ICOS ligand (ICOSLG, ICOSL or GL50) is a protein that in humans is encoded by the ICOSLG gene located at chromosome 21. Enables identical protein binding activity. Predicted to be involved in T cell receptor signaling pathway and positive regulation of interleukin-4 production. Located in cytoplasmic ribonucleoprotein granule and plasma membrane.

Gene Full Name: inducible T cell costimulator ligand

Gene ID: 23308

UniProt: O75144

Pathways: Production of Molecular Mediator of Immune Response, Activated T Cell Proliferation
