If possible, all incubation steps should be performed on an orbital shaker to equilibrate solutions when added to the microplate wells. Also, all provided solutions should be at ambient temperature prior to use.

1.Average the duplicate or triplicate readings for each standard, control and sample and subtract the average zero standard optical density.
2.Generate a standard curve by using Microsoft Excel or other computer software capable of establishing a 4- Parameter Logistic (4-PL) curve fit.

Reagents provided in this kit may be harmful if ingested, inhaled or absorbed through the skin. Please carefully review the MSDS for each reagent before conducting the experiment.
Stop Solution contains 2 N Sulfuric Acid (H2SO4) and is an extremely corrosive agent. Please wear proper eye, hand and face protection when handling this material. When the experiment is finished, be sure to rinse the plate with copious amounts of running water to dilute the Stop Solution prior to disposing the plate.

Human 4-1BB Ligand Receptor, also known as the Tumor Necrosis Factor Receptor Superfamily Member 9, is a 255 amino acid cytokine protein implicated in T-cell activation pathways. After initial synthesis of the peptide, the cytokine is proteolytically cleaved by proteases, thus separating the 23 residue signal sequence from the actual mature 232 residue 4-1BB Receptor sequence. The protein is expressed from the TNFRSF9 gene located at locus 1p36 on chromosome 1.

Cancer Immune Checkpoints

This particular immunoassay utilizes the quantitative technique of a Sandwich Enzyme-Linked Immunosorbent Assay (ELISA) where the target protein (antigen) is bound in a sandwich format by the primary capture antibodies coated to each well-bottom and the secondary detection antibodies added subsequently by the investigator. The capture antibodies coated to the bottom of each well are specific for a particular epitope on the Human 4-1BBR cytokine while the user-added detection antibodies bind to epitopes on the captured target protein.
