More Details

  • ASPARAGINASE (EC is a key enzyme in the metabolism of asparagine. Its principal use is as treatment for acute lymphoblastic leukemia and lymphoblastic lymphoma where the asparagine is an essential amino acid. BioAssay Systems’ DASN-100 Kit provides a convenient fluorimetric method to measure asparaginase 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 20 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 Km of my Asparaginase?

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

Does your kit include Asparaginase enzyme?

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