Lobaric acid

Customer Review

Based on 1 Customer Validation

Lobaric acid is a depsipeptide metabolite isolated from Stereocaulon lichen with antioxidant, antiproliferative, antiviral and enzyme inhibitory activities. Lobaric acid scavenges superoxide free radicals (IC₅₀=97.9 μM) and inhibits cancer cell proliferation (EC₅₀ of 15.2-63.9 μg/mL against leukemia, colorectal, gastric, breast, ovarian, prostate, pancreatic and lung cancer cell lines). Lobaric acid inhibits protein tyrosine phosphatase 1B (PTP1B; IC₅₀=0.87 μM for human recombinant enzyme) and 12(S)-HETE produced by 12(S)-lipoxygenase (IC₅₀=28.5 μM). Lobaric acid (250 μM) also reduced pathological changes in tobacco leaves infected with tobacco mosaic virus (TMV).

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.
