Elastase expression assay (ELAS)

Elastase is an inflammatory protease expressed in immune cells. Elastase contributes to the immune defense by inactivating foreign bacteria but causes damage to connective tissue and breaks down cytokines, immunoglobulins and immune cells receptors at the same time.

RNA-based tests : One TempusTM tube. Stable for 72 hours at ambient temperature. For longer periods freeze and ship at -20°C

  • An excessive, chronic production of elastase is therefore detrimental. The expression of mRNA can be quantified as a specific marker of inflammation.

Data sheet
Do I need to prepay the test before receiving the kit?

No, we will send you an invoice once we receive your sample. All payment instructions are listed on the invoice. You can pay by wire transfer or credit card (VISA or Mastercard only). Please kindly note that checks are no longer accepted. The analysis report will be released only if the tests are paid.

What is the turnaround time for the tests?

It will take approx. 4 weeks to get the results from all tests, except for MSA (6 weeks) and CD56 and CD57 (48 -72 hours).
