More Details

• GLUTAMINASE (EC 3.5.1.2) is a key enzyme in the metabolism of glutamine. Glutamine is an important amino acid in the metabolism of cancer cells, and increased glutaminolysis has been linked to cancer. BioAssay Systems’ DGLN-100 Kit provides a convenient fluorimetric method to measure glutaminase activity in biological samples. In this assay, o-phthalaldehyde reacts with liberated ammonia where the increase in fluorescence at λex/em = 415/475 nm is directly proportional to enzyme activity.

Can the kit?s sensitivity be increased?

Yes, you can increase the enzyme incubation step from 30 minutes to a time that provides detectable activity. The incubation time with the detection reagent will remain the same (20 minutes). Be sure to adjust the incubation time included in the calculation to represent the time you actually used.

Can I use this kit to determine the K_m of my Glutaminase?

Yes, you can use this kit to determine the enzymatic parameters of your Glutaminase. The kit comes with a 20 mM Stock solution of the Glutamine substrate. You can use different dilutions of the substrate to generate the enzymatic parameters of your Glutaminase.

Does your kit include Glutaminase enzyme?

Our kit does not include enzyme. The customer needs to provide their enzyme of choice for this assay.
