Description

Application

Chlortetracycline was used in fluorescence assays to detect the Ca+2 influx required for the completion of acrosome reaction in human spermatozoa.

Biochem/physiol Actions

Chlortetracycline is an antibiotic produced by some strains of Streptomyces aureofaciens. It inhibits protein synthesis (elongation) by preventing binding of aminoacyl-tRNA to the 30S subunit. It is effective against Gram-positive and to a lesser degree Gram-negative bacteria than tetracycline.
Mode of Resistance: Loss of cell wall permeability.

Packaging

5, 25, 100 g in glass bottle

General description

Chemical structure: tetracycline

Other Notes

If stored frozen, chlortetracycline hydrochloride is expected to remain stable at least four years.
