Descrição geral

Chemical structure: ß-lactam

Embalagem

5, 25, 100 g in poly bottle

Aplicação

Used to select for ampicillin resistance in mutated and transformed cells.

Ações bioquímicas/fisiológicas

Mode of Action: This is a ß-lactam antibiotic that inhibits bacterial cell-wall synthesis by inactivating transpeptidases on the inner surface of the bacterial cell membrane.

Mode of Resistance: Administration with ß-lactamase cleaves the ß-lactam ring of Ampicillin and inactivates it.

Antimicrobial Spectrum: Includes both gram-positive (similar to benzylpenicillin) and gram-negative bacteria (similar to tetracyclines and chloramphenicol.

Atenção

This product has been reported stable as supplied at 25°C at 43% and 81% relative humidity for six weeks. Additional studies have shown that the stability of Ampicillin in solution is a function of pH, temperature and the identity of the buffer. It′s activity is quickly lost when stored above pH 7. Optimal storage conditions are suggested as 2-8°C, and pH 3.8-5 where its activity was retained at 90%+ for a week.

Nota de preparo

Ampicillin is reported as slightly soluble in water, practically insoluble in alcohol, chloroform, ether and fixed oils but soluble in dilute acids or bases. The solution should not be autoclaved; a stock solution should be sterilized through filtration and stored frozen, where it will be stable for months.

Outras notas

Keep container tightly closed in a dry and well-ventilated place. Storage class (TRGS 510): Non Combustible Solids

Certificado de análise

Certificado de origem

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. What is the solubility of Product A9518, Ampicillin sodium salt?

    This product is soluble in water at a concentration of 50 mg/mL, producing a clear, colorless to faint yellow solution.  

  3. Is Ampicillin product stable in solution?

    We recommend using freshly prepared solutions. A concentrated solution of sodium ampicillin in water (approximately 330 mg/mL) may be expected to lose about 10% potency in 20 hours at -20°C.

  4. How do I use Ampicllin in agar plates?

    For plates, add ampicillin to autoclaved media cooled to 48°C, to a final concentration of 35-50 μg/mL. Pour the plates, and allow them to cool completely. Plates may be stored at 2-8°C for up to only 1-2 weeks before use.

  5. How do I get lot-specific information or a Certificate of Analysis?
