Detection Principle | LAP can catalyze the substrate L-leucine-4-nitroaniline to produce p-nitroaniline, which has the maximum absorption peak at the wavelength of 405 nm. The enzyme activity of LAP can be calculated by measuring the increasing OD value of the system. |

The recommended dilution factor for different samples is as follows (for reference only):
Sample Type | Dilution Factor |
---|---|
Human serum | 1 |
Dog serum | 1 |
Rat serum | 1 |
Cynomolgus monkey serum | 1 |
10% Rat spleen tissue homogenate | 1 |
10% Rat liver tissue homogenate | 1 |
10% Rat kidney tissue homogenate | 1 |
10% Rat lung tissue homogenate | 1 |
The diluent is normal saline (0.9% NaCl) or PBS (0.01 M, pH 7.4). For the dilution of other sample types, please do pretest to confirm the dilution factor.
