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