Allgemeine Beschreibung

Chemical structure: tetracycline

Anwendung

Cell-permeable fluorescent probe for Ca2+ for measuring calcium flux in endoplasmic reticulum and other intracellular stores in situ.

Biochem./physiol. Wirkung

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.

Sonstige Hinweise

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

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

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

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 objective of this study was to determine the mechanism by which RU 486 (mifepristone) protects sperm to undergo premature capacitation during cryopreservation. For this, semen ejaculate (n = 20) was divided into four equal fractions and diluted using egg yolk-based extender
