Emestrin

Emestrin is a mycotoxin originally isolated from E. striata that has antimicrobial, immunomodulatory, and cytotoxic activities. It is active against the fungi C. albicans and C. neoformans, as well as the bacteria E. coli, S. aureus, and methicillin-resistant S. aureus (MRSA; IC₅₀s=3.94, 0.6, 2.21, 4.55, and 2.21 μg/mL, respectively).2 Emestrin is a chemokine (C-C motif) receptor 2 (CCR2) antagonist (IC₅₀=5.4 μM in a radioligand binding assay using isolated human monocytes).3 Emestrin (0.1 μg/mL) induces apoptosis in HL-60 cells. It induces heart, thymus, and liver tissue necrosis in mice when administered at doses ranging from 18 to 30 mg/kg.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
