Gold Biotechnology Inc Ampicillin (Sodium), USP Grade 100 g

Ampicillin sodium is a member of the extended-spectrum β-lactam family and similar in structure to penicillin. It is used in the selection of antibiotic cell hybrids and has a high rate of action against many gram-negative bacterial strains. Ampicillin sodium targets non-ESBL (Extended Spectrum β-lactamase) bacteria including Staphylococcus and Streptococcus species and medically important enteric pathogens such as Shigella and Salmonella. It has been found to be effective against certain β-lactam sensitive VRE or vancomycin resistant Enterococcus species. Resistance to ampicillin is routinely utilized as a selectable marker to confirm successful cell transformation. Ampicillin Sodium is freely soluble in water.

Research Products International Corp Actinomycin D [Actinomycin C1] [Dactinomycin], 5 Milligrams

Actinomycin D, also known as Dactinomycin, is an antibiotic.

It works by binding to DNA, inhibiting both DNA and RNA synthesis. This interference with nucleic acid synthesis makes it effective against rapidly dividing cells, such as cancer cells.

Actinomycin D is used as a tool to study DNA and RNA synthesis, cell cycle progression, and cellular responses to DNA damage. Its ability to interfere with nucleic acid synthesis makes it valuable in understanding the molecular mechanisms of cell biology and cancer.

WARNING! This product can expose you to Actinomycin D, a chemical which is known to the State of California to cause cancer and developmental harm. For more information go to www.P65Warnings.ca.gov.
