1-l) Glucose

When a sample is mixed with the Choromogen Reagent, the a-form of glucose in the sample is converted to β-form by mutarotase. β-D-Glucose is oxidized and yields hydrogen peroxide by glucose oxidase (GOD). In the presence of peroxidase (POD), the formed hydrogen peroxide yields a red pigment by quantitative oxidation condensation with phenol and 4-aminoantipyrine. The glucose concentration is obtained by measuring absorbance of the red pigment. [

1-m) Leptin


Leptin, secreted from fatty cells, is known as a hormone controlling body fat by suppression of eating and increase of energy metabolism. It is reported, however, that expression of leptin gene in fatty tissue and concentration of leptin in blood are at high levels in obese people and model animals of obesity.
[Principle of the assay]
This kit is a sandwich-format of ELISA with two antibodies specifi c to rat leptin. Monoclonal antibody to leptin is coated on the microplate well, which captures leptin in sample. Following reaction with HRP-conjugated rabbit anti rat leptin antibody, forms HRP labeled antigen-antibody complex on the well, which reports the signal of leptin amount in the sample by chromogenic reaction associated with catalysis of hydrogen peroxide.
Dynamic range :
. Samples for serum and plasma : 312.5 ~ 20,000 pg/mL
. Samples for others than serum and plasma : 78.1 ~ 5,000 pg/mL

Specifi c to rat Leptin, but only slightly cross-reactive to human Leptin.
