Calibrant/Colorimetric Assay Method for the determination of NAG (N-Acetyl-β-D-glucosaminidase).

Description Product Code
300 test kit or 50 manual test kit* 1085
300 test kit (equivalent to 50 manual tests) 1290050
600 test kit (equivalent to 100 manual tests) 1290100
Calibrant 1290011

*Unlike 1290100 and 1290050 kits, Buffer A is divided into five bottles, this allows small batches of samples to be run at different times and is ideal for initial studies as N + A solution once mixed is only stable for 5 days.

Two controls are supplied in each kit.
