Its been some time since i worked with enzymes. So as i now had a look at Enzymes by several vendors i wondered about the units the activity was given in and their meaning.
e.g browsing Novozymes products you find activity in units such as
LU/g
IUN/g
PLU/g
KLU/g
ECU/g
AU-A/g
KNPU-E/g
LAM/g
KNPU-S/g
Just looking at their enzymes for yeast extracts (https://biosolutions.novozymes.com/en/animal-protein/other-protein-sources) you can find
AU-A/g
LAPU/g
Prot/g
CPDU(A)/g
EGLU-A/g
Some companies use the good old U/g - but in all those cases i couldnt find any information how to determine the amount of enzyme that might be needed.
Do you know what those units mean, how they are measured etc?
Usually, the datasheet should give you information about how the units are measured. Frequently, there are different methods to assess enzyme activity (e.g. different pH, different Temperature, different substrates, etc.), so we end up with different ways to tell activity.
Often commercial vendors continue to use the unit definitions that are found in the literature, hence the same company might have different definitions for different products. But as Wolfgang Schechinger mentioned, each should be well explained on that product's data sheet.
