Based on 1 publication(s) in Google Scholar

Fluorescent brightener 28 (Technical Grade) is a fluorescent whitening agent commonly used in the padding process of the textile industry. Fluorescent brightener 28 is capable of staining polysaccharides such as cellulose, and when the plasma membrane ruptures, it also weakly stains the cytoplasm and strongly stains the cell nucleus. Additionally, Fluorescent brightener 28 can be utilized to detect intracellular chitin in living cells. Fluorescent Brightener 28 also is a visible light emitting diode (LED)-light sensitive photoinitiator for free radical photopolymerizations.

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.
