General description
A reversible inhibitor of trypsin-like proteases and cysteine proteases. Also known to inhibit activation-induced programmed cell death and to restore defective immune response in HIV+ donors. Often used for the inhibition of endoproteinase Lys-C, kallikrein, papain, plasmin, thrombin, cathepsin B, and trypsin. Leupeptin does not inhibit chymotrypsin, elastase, renin, or pepsin. The recommended working range is 10-100 µM for most applications.
A reversible inhibitor of trypsin-like proteases and cysteine proteases. Also known to inhibit activation-induced programmed cell death and to restore defective immune responses of HIV+ donors. Also available as a 50 mM solution in H2O (Cat. No. 509281).

HIV-associated neurocognitive impairment (HIV-NCI) is a debilitating comorbidity that reduces quality of life in 15-40% of people with HIV (PWH) taking antiretroviral therapy (ART). Opioid use has been shown to increase neurocognitive deficits in PWH. Monocyte-derived macrophages (MDMs) harbor HIV

Lysine acetylation has been discovered in thousands of non-histone human proteins, including most metabolic enzymes. Deciphering the functions of acetylation is key to understanding how metabolic cues mediate metabolic enzyme regulation and cellular signaling.
