Tnf α kit

Manufactured by Thermo Fisher Scientific
Sourced in United States

The TNF-α kit is a laboratory assay designed to detect and quantify the presence of the tumor necrosis factor alpha (TNF-α) protein in biological samples. TNF-α is a key cytokine involved in inflammatory and immune responses. The kit uses a sandwich ELISA (Enzyme-Linked Immunosorbent Assay) format to measure TNF-α concentrations in the sample.

Levels of inflammatory factors were measured by ELISA with Interleukin- 6 (IL-6) kit (MAN0017508, 88-7064) and tumor necrosis factor-α (TNF-α) kit (MAN0017423, 88-7324) purchased from Thermo Fisher Scientific (Massachusetts, America). Heart tissue was cut up, added to nine times the volume of PBS (pH = 7.4), transferred to a glass homogenizer and made into a 10% homogenate on ice, then further ground using ultrasonic fragmentation. The prepared tissue homogenate was centrifuged at 5,000 r for 5 min and the supernatant was taken as reserve. Dilute the antibody with carbonate-coated buffer to a protein content of 10 μg/ml. Antibodies, enzyme conjugates and chromogenic substrates were added according to the instructions of the kit, and the optical density value of each well was measured at 450 nm using a microplate reader after termination.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
