Principle
Amylase test involves use of a chromogenic substrate Gal G, – a CNP (2-chloro-4-nitrophenyl linked with galactosyl maltoside). The direct action of amylase with this substrate results in the release of more than 90% of 2-chloro-4-nitrophenol, which can be monitored by kinetic assay at 405 nm. The increase in absorbance is directly proportional to the amylase activity in the sample.

Quality Control
To ensure adequate quality control, it is recommended that
each laboratory should use a normal and an abnormal
commercial reference control material. It should be realized
that the use of quality control material checks both reagent
and instrument functions together. Factors which might affect
the performance of this test include instrument function,
temperature control, cleanliness of glasswares and accuracy
of pipetting.
Other Details
The kit components should be stored at 2-8°C and is stable til the expiry date indicated on the label. t is recommended to store the reagents at 2-8°C, tightly closed after use.
The working solution (4R1 + 1R2) is to be prepared fresh as per the
requirement.
DO NOT FREEZE THE REAGENTS. Frozen Latex or Diluent could change the functionality of the test.
Contamination of the reagent should be strictly avoided.
