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 bacterial than tetracycline.Mode of Resistance: Loss of cell wall permeability. 包装 5, 25, 100 g in glass bottle
