resDetect™ Anti-CD28 Antibody ELISA Kit

产品描述（Product Details）

背景（Background）

Similar to CD3 antibody, CD28 antibodies also can be used to stimulate the proliferation and activation of T cells in CIK cell therapy. Under the cooperation of other cytokines, such as IL2 and IL1a, CIK cells with rapid proliferation, high tumoricidal activity, broad tumor killing spectrum and non-MHC-restricted tumor killing characteristics are generated, which has significant effects on the treatment of cancer, chronic leukemia, liver disease and neurological diseases. Obviously, It is necessary to control the residues of raw materials in the final cell therapy products.

应用说明（Application）

The kit is developed for the detection of anti-CD28 antibody in Bioprocess manufacturing applications. It is used as a tool to aid in routine quality control of in-process streams as well as final product.

It is for research use only.

组分（Materials Provided）

原理（Assay Principles）

This assay kit employs a standard indirect-ELISA format, providing a rapid detection of Anti-CD28 antibodies. The kit consists of Pre-coated Human CD28 Microplate and Anti-CD28 Antibody Standard and HRP-Anti-Mouse IgG secondary antibody and related buffer.

Your experiment will include 5 simple steps:

a) All reagents were returned to room temperature(20℃-25℃) before use.

b) Add your sample to the plate, take the Anti-CD28 Antibody as standard sample. The samples and standard sample are diluted by Dilution Buffer.

c) Wash the plate and add a diluted HRP-Goat anti-Mouse IgG to the plate. The diluted by Dilution Buffer.

d) Wash the plate and add TMB.

e) Stop the substrate reaction by add diluted acid. Absorbance (OD) is calculate as the absorbance at 450 nm minus the absorbance at 630 nm to remove background prior to statistical analysis. The OD Value reflects the amount of Antibody bound.
