Scytonemin

Customer Review

Based on 1 Customer Validation

Scytonemin is a hydrophobic alkaloid pigment that can be isolated from the outer sheath of cyanobacteria. Scytonemin has protective function against short-wave solar ultraviolet (UV) radiation, which can reduce the generation of reactive oxygen species (ROS) and the formation of DNA damage. Scytonemin also has anti-inflammatory and anti-proliferative activities, produces concentration-dependent inhibition (IC₅₀=2.0 μM) of polo-like kinase 1 (PLK1)-mediated cdc25C phosphorylation, and plays an important role in regulating the G2/M transition in the cell cycle. It can be used in the research of cancer, acute inflammation and sunscreen cosmetics.

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.
