General description

Chemical structure: tetracycline

Application

Cell-permeable fluorescent probe for Ca2+ for measuring calcium flux in endoplasmic reticulum and other intracellular stores in situ.

Biochem/physiol Actions

Chlortetracycline is an antibiotic produced by some strains of Streptomyces aureofaciens.
Mode of Action: Inhibits protein synthesis (elongation) by preventing binding of aminoacyl-tRNA to the 30S subunit.
Antimicrobial spectrum: Gram-positive. Less active against Gram-negative bacteria than tetracycline.
Mode of Resistance: Loss of cell wall permeability.

Packaging

5 g, 25 g, 100g

Quality

Recommended for fluorescent studies of calcium signaling in cells or tissues.

Other Notes

Keep container tightly closed in a dry and well-ventilated place.

The effect of temperature on the binding equilibria of calcium-sensing dyes has been extensively studied, but there are also important temperature-related changes in the photophysics of the dyes that have been largely ignored. We conducted a systematic study of thermal
