Rhodamine B ethyl ester

Rhodamine B ethyl ester is a hydrophilic cationic derivative of Rhodamine B (HY-Y0016), belonging to non-selective cytotoxic agents and transporters. Rhodamine B ethyl ester exhibits broad-spectrum in vitro cytotoxicity and exerts cytotoxic effects on human tumor cells. Rhodamine B ethyl ester binds effectively to lipid membranes, undergoes voltage-dependent transport across planar bilayer phosphatidylcholine membranes, and its transport can be determined by current relaxation after voltage jump. Rhodamine B ethyl ester can be used in research related to cancers such as epithelioid melanoma and colorectal adenocarcinoma.

In Vitro

Rhodamine B ethyl ester (compound 1) exhibits cytotoxicity against human tumor cell lines A375, HT29, MCF-7, A2780 and FaDu, as well as non-malignant NIH 3T3 mouse fibroblasts, with EC₅₀ values ranging from 0.21 μM (A2780) to 0.96 μM (NIH 3T3), and shows low selectivity^[1].
Rhodamine B ethyl ester (C₂RB) (0.2 μM) can translocate across DPhytanylPC planar bilayers, with a translocation rate constant of 1.1 s⁻¹ and a characteristic relaxation time of 0.12 s under a 100 mV voltage jump^[2].
Rhodamine B ethyl ester shows slower translocation rates in ester-type planar bilayer membranes (DPhPC, DOPC, DEPC) than in ether-linked DPhytanylPC bilayers, and its characteristic relaxation time rises as the fatty acid chains of membrane lipids get longer under a 100 mV voltage jump^[2].

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.
