DSPE-PEG2000-FITC

Customer Review

Based on 1 Customer Validation

DSPE-PEG2000-FITC is a PEG lipid conjugated with fluorescein. FITC is a green dye with a peak absorption at 494 nm and a maximum emission at 520 nm, which is used for staining biological samples or nanoparticles. DSPE-PEG2000-FITC spontaneously forms lipid bilayers or micelles in water and can be used to prepare liposomes for delivering substances such as mRNA vaccines.

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.
