Cat. No.: HY-D0040
CAS No.: 1461-15-0
Synonyms: Fluorexon
Calcein is a fluorescent dye and self-quenching probe, used as an indicator of lipid vesicle leakage, and also as a complexometric indicator for titration of calcium ions with EDTA, and for fluorometric determination of calcium. Calcein cannot directly cross the intact cell membrane of a living cell, unlike Calcein-AM (HY-D0041) which is cell-permeable. Calcein can also be used as a model drug for evaluating efficiency and bioavailability of drug delivery systems .

Eriochrome black T, Indicator is a complexing agent for metal ions (e.g., Ca 2+, Mg 2+) and is used as an indicator in complexometric titrations. Eriochrome black T, Indicator forms colored complexes with metal ions through covalent coordination bonds, and indicates the endpoint of the titration by color change. Eriochrome black T, Indicator can be used as an anionic azo dye in photocatalytic degradation studies to evaluate the performance of photocatalysts. The reaction solution of Eriochrome black T, Indicator combined with Mg 2+ is initially purple. During loop-mediated isothermal amplification (LAMP), the color changes from purple to sky blue due to the consumption of Mg 2+ by the formation of magnesium pyrophosphate, indicating a positive reaction. The optimal concentration of Eriochrome black T, Indicator in LAMP is 60 μM, and the detection limit for Mycobacterium tuberculosis is 1 pg DNA/reaction .

HEPPSO is a zwitterionic Good's buffer suitable for physiological pH conditions. HEPPSO forms high-order oligomers in aqueous solutions and can form a 1:1 complex with Cu 2+ via its hydroxyalkyl and tertiary amine groups. However, HEPPSO contains a structurally similar trace impurity lacking an alkanesulfonic acid side chain. The complex formed by this impurity and Cu 2+ has a very low Ka; therefore, HEPPSO may interfere with studies on copper speciation analysis in natural water bodies .
