Leptin immunoassay kit

Manufactured by R&D Systems

The Leptin Immunoassay Kit is a quantitative sandwich enzyme immunoassay designed for the measurement of leptin levels in biological samples. The kit utilizes a monoclonal antibody specific for leptin that is pre-coated onto a microplate. Samples and standards are pipetted into the wells, and any leptin present is bound by the immobilized antibody. After washing, an enzyme-linked polyclonal antibody specific for leptin is added to the wells. Following a wash to remove any unbound antibody-enzyme reagent, a substrate solution is added and color develops in proportion to the amount of leptin bound. The intensity of the color is measured.

Serum insulin and leptin levels were quantified by a mouse insulin ELISA kit (Mercodia) and a leptin immunoassay kit (R&D Systems), respectively. Serum ALT and AST levels were quantified using the transaminase CII-test Wako kit (Wako).

Leptin Immunoassay Protocol for Adipose Tissue

Check if the same lab product or an alternative is used in the 5 most similar protocols
Leptin levels were determined using a leptin immunoassay kit (R&D Systems, Inc., Minneapolis, MN) according to the manufacturer’s protocol. The peri-renal AT was homogenized in lysate buffer (dilution buffer, included in the assay kit and protease inhibitor) at 500 μL per 100 mg of AT on ice and then centrifuged twice to remove lipids and debris. Rat serum was diluted 5 fold in dilution buffer, while AT was diluted 15-fold, and the supernatant containing adipocytes 4-fold.

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.
