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.

Chlorotetracycline (CTC) is one of the most antibiotics present in cattle manure. In present study, three levels of CTC (0, 20 and 40 mg kg-1) were added to cattle manure composting systems to investigate its effects on the distribution of antibiotic-resistant genes

Cellular processes are largely carried out by macromolecular assemblies, most of which are dynamic, having components that are in constant flux. One such assembly is the nuclear pore complex (NPC), an ∼50 MDa assembly comprised of ∼30 different proteins called

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

Many studies suggest that endoplasmic reticulum (ER) Ca2+ pool rather than cytosolic Ca2+ may play a crucial role in triggering apoptosis. In this study, we performed an image analysis of cells loaded with the fluorescent dye chlortetracycline (CTC) to in
