Cathepsin L1, a major cysteine protease secreted by the parasite plays a pivotal role in various aspects of its pathogenicity. For example, Cathepsin L1 takes part in nutrient acquisition by catabolizing host proteins to absorbable peptides, facilitates the migration of the parasite through the host intestine and liver by cleaving interstitial matrix proteins such as fibronectin, laminin, and native collagen, and is implicated in the inactivation of host immune defenses by cleaving immunoglobulins. Cathepsin L1 suppresses Th1 immune responses in infected laboratory animals making them susceptible to concurrent bacterial infections[1].

  • Dilution Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
