Antibody Array Platform for CRS Cytokine Analysis

All products and services are For Research Use Only and CANNOT be used in the treatment or diagnosis of disease.

Valuable Tool for Studying Cytokines

Cytokine Release Syndrome (CRS) is acute systemic inflammation associated with treatments from therapeutic antibodies, CAR-T cell therapy, and even haploidentical marrow transplantations. During CRS, a large number of cytokines are rapidly released into the bloodstream from immune cells affected by the immunotherapy. Symptoms may range from headache and fever to organ damage or even death. The Human Cytokine Antibody Arrays facilitate study of the cytokine network by allowing you to monitor the relative abundance of certain human cytokines from a variety of sources in a high-throughput manner.

Creative Biolabs'human antibody arrays platform bring cytokine detection to a new level. With this system, you can rapidly and accurately profile the expression of multiple cytokines–at the protein level–in the range of picogram per mL. Use the human antibody arrays to determine human cytokine content in serum, plasma, and conditioned media.

Principle of the Human Antibody Array

The human cytokine antibody arrays are based on the sandwich ELISA method for detecting protein. First, a capture antibody specific to a particular cytokine protein is immobilized on the array membrane. Second, sample is incubated with the capture antibody, proteins are given time to bind, and any unbound protein is washed away. Then, a second antibody, known as the detection antibody, is introduced. This biotin-conjugated antibody binds to a second epitope on the protein, creating an antibody "sandwich" around the cytokine. Through a biotin-strepavidin interaction, an enzyme is used to visualize the bound cytokine protein. The linkage between capture antibody, target protein, and detection antibody offers a high degree of selectivity and sensitivity.
