Bis(12-crown-4), a sodium ionophore, is 1 times more selective for sodium than potassium in the PVC electrode using NPOE as a plasticizer.

Application:Zn2+ detection, colorimetric

Application: Cu(I) determination, colorimetric

BIGCHAP and deoxy-BIGCHAP are non-ionic detergents based on a cholic acid and a bisglucon-amidopropyl group.

BCECF-AM is an acetoxymethyl ester of BCECF that enables easy loading of BCECF into cells. BCECF-AM accumulates in a cell only by incubation as do the other acetoxymethyl esters. BCECF-AM is very sensitive to moisture; it should be carefully handled.

Biotin-PE-maleimide can be solubilized in PBS at pH 7.4 to prepare 2 mM solution without using an organic solvent. The reactivity of maleimide with sulfhydryl groups is higher than that of bromoacetamide, so the required concentration of maleimide biotin is much lower than that of bromoacetamide biotins.

- Simple preparation of Biotin-SAM on gold surface - Efficient Immobilization of Avidins - Suppress unspecific binding with unknown proteins

Application: EPR (ESR) Detection, Superoxide anion radical - Long half-life - High solubility in water - Greater S/N ratio
