Megazyme produces 5 acetic acid test kits:
K-ACET: uses the traditional Acetyl CoA synthetase (ACS) reaction. Positive reaction (increasing absorbance). Does not use an end-point reaction. Manual format for use with spectrophotometers.
K-ACETRM: uses the more recently developed and more rapid acetate kinase (AK) reaction with an end-point reaction. Less component additions and more tests per kit. Negative reaction (decreasing absorbance). Manual format for use with spectrophotometers.
K-ACETAF: uses the traditional Acetyl CoA synthetase (ACS) reaction. Positive reaction (increasing absorbance). Automated format for use with auto-analysers or microplate.
K-ACETAK: uses the more recently developed and more rapid acetate kinase (AK) reaction. Negative reaction (decreasing absorbance). Automated format for use with auto-analysers or microplate.
K-ACETGK: uses the most recently developed and more rapid ADP-GK reaction with AK. It is a positive reaction and therefore more robust. Automated format for use with auto-analysers.
