Product Specifications

Immunogen

S. frugiperda ovarian cell line Sf 21-derived Insect Cathepsin L

Specificity

Detects pro form of Insect Cathepsin L in direct ELISAs and Western blots. In Western blots, less than 5% cross-reactivity with recombinant human (rh) Cathepsin S is observed and no cross-reactivity with rhCathepsin B, F, K, L2/V, and activated, mature insect Cathepsin L is observed.

  • 6 months, -20 to -70 °C under sterile conditions after reconstitution.

Background: Cathepsin L

The pro form of insect cell Cathepsin L is stable at neutral pH, but autoactivates in acidic buffers under reducing conditions. The activated enzyme is similar in substrate specificity to mammalian Cathepsin L, and is very active as a protease, as judged by its ability to degrade azocasein. Cystatins A, B, C, E/M, F, SA, and SN are potent inhibitors of the insect cell Cathepsin L. Like other cysteine proteases related to papain, insect cell Cathepsin L is also inhibited by E-64 and reagents which react with thiols.
