Leucine amino peptidase (LAP)

L-Type LAPFor In Vitro Diagnostic Use

Intended Use

L-Type LAP is an in vitro assay for the quantitative determination of the activity of Leucine aminopeptidase (LAP) in serum or plasma.


L-leucyl-p-nitroanilide substrate method

Special Characteristics

Good stability after opening. 
Calculate the measured K factor with 4-nitroaniline for setting the calibration coefficient of our product.

Principle of the Method

When a sample is allowed to act on L-leucyl-p-nitroanilide in phosphate buffer, p-nitroaniline is released by leucine aminopeptidase in the sample. The leucine aminopeptidase activity value in the sample is determined by measuring the production rate of this p-nitroaniline.
