描述

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.

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.
