BioSupply offers a highly sensitive and specific leptin ELISA kit. This assay provides a dynamic range of 62.5-4,000pg/ml and it can reach minimum sensitivity detection limits of <10pg/ml. Leptin is a protein which is 16kDa in size and consists of a single 146 amino acid sequence, this is predominately the product of the obese gene. Whilst leptin is circulating around the body, it is abundantly expressed in the adipose tissues where it is critical in regulating appetite, fat metabolism and body weight. In humans, it has been found that the amount of leptin present is directly correlated with the percentage of body fat and BMI. Both of these factors are well known to be elevated in people who are obese. For more information on this product, please visit our website: http://www.elisakits.co.uk/leptin-elisa-kit/
