Ampicillin Sodium salt is an antibiotic in the broad-spectrum penicillin group. Ampicillin differs from penicillin only by the presence of an amino group, which facilitates penetration through the outer membrane of some gram-negative bacteria. Ampicillin acts by interfering directly with the turnover of the bacterial cell wall and indirectly by triggering the release of enzymes that further alter the cell wall.
Ampicillin is an antibiotic used to inhibit cell wall biosynthesis by interrupting peptidogly can cross-linking. Ampicillin can be used in cell culture applications.
Ampicillin Sodium Salt is in powder form which makes it an economical choice that can be used in a wide range of gram-positive and gram-negative infections.

Typical stock solution
The ampicillin powder is used to make a stock solution at 50mg/ml in water. The working concentration for stringent plasmids is 20 µg/ml and 60 µg/ml for relaxed plasmids.
Stock solutions of ampicillin dissolved in water should be sterilized by filtration through a 0.22 micron filter.
Capsaicinoids are produced by plants in the Capsicum genus and are the main reason for the pungency of chili pepper fruits. They are strong agonists of TRPV1 (the transient receptor potential cation channel subfamily V member 1) and used as active ingredients in pharmaceuticals for the treatment of pain. The use of bioengineered microorganisms in a fermentation process may be an efficient route for their preparation, as well as for the discovery of (bio-)synthetic capsaicinoids with improved or novel bioactivities.
