LipoFluor-ER1™ is a cell-permeant stain for the endoplasmic reticulum. LipoFluor-ER1™ passively diffuses across the plasma membrane into the cell, stains at low concentrations and has minimal cytotoxic effects. It can be used as a real-time imaging reagent which can be imaged within minutes of addition and has minimal photobleaching. LipoFluor-ER1™ is easily washed from cells, and therefore is ideal for protocols which require intermittent monitoring of endoplasmic reticulum structures. This tracing reagent can be used on live and fixed samples and is compatible with other dyes. LipoFluor-ER1™ has a large Stokes Shift, shows excellent resistance to photobleaching and demonstrates low cytotoxicity.
Application(s)IF, ICC, Live Cell IF
SpecificityFluorescent imaging of the endoplasmic reticulum compartment. Cell penetration and localisation of LipoFluor-ER1™ has been confirmed in a range of cell lines, including prostate cells (PNT2, PNT1a, LNCaP, 22RV1 and DU145), cardiomyocytes (H9c2) and neuronal cells (PC-12).
Species ReactivityHuman, Mouse, Other Mammals, Rat
Concentration50mM
Purity DescriptionThin layer chromatography using alumina plates and a solvent system of ethanol and water (3:1) revealed the presence of fluorescent isomers. No amount of starting material was detected.

The typical working concentration is 50µM (1:1000 dilution) in an appropriate buffer or cell culture medium. Biosensis recommends that the end user determine optimal dilutions/concentrations.
