General description
Chemical structure: tetracycline
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.
Mode of Resistance: Loss of cell wall permeability.
Other Notes
If stored frozen, chlortetracycline hydrochloride is expected to remain stable at least four years.

Cyclodextrin, which stimulates cholesterol efflux from cells, was examined for its ability to induce capacitation of mouse spermatozoa. A chemically defined, protein-free medium was used for in vitro fertilization of cumulus-free mouse eggs. Fertilization did not occur in modified Krebs-Ringer

This study was designed to compare three different fluorescent probes to assay the acrosome reaction in human spermatozoa: chlortetracycline (CTC), mannosylated bovine serum albumin (BSA) labelled with fluorescein (MAF), and quinacrine (QN). Normal human sperm ejaculates were washed and allowed

Most laboratory methods used to evaluate semen quality have not correlated highly with fertilizing capacity. The discovery of a variety of fluorochromes and compounds conjugated to fluorescent probes has enabled a more widespread analysis of sperm attributes, and in conjunction

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
