Research Products International Corp Amphotericin B, 5 Grams

Amphotericin B is a polyene antifungal agent known for its efficacy against a broad spectrum of fungi, including yeast and molds. It functions by binding to the fungal cell membrane, forming pores that disrupt membrane integrity. This disruption leads to the leakage of cellular contents, ultimately causing fungal cell death.

Amphotericin B is commonly used to prevent and treat fungal contamination in cell cultures and microbiological experiments. It is added to growth media to maintain aseptic conditions and protect cell lines from fungal overgrowth.

The antifungal activity of Amphotericin B makes it a valuable tool in maintaining the integrity of cell cultures and ensuring reliable experimental results.

Research Products International Corp Methicillin Sodium Salt, 1 Gram

Methicillin Sodium Salt is a chemical compound that belongs to the class of beta-lactam antibiotics known as penicillin.

It is a modified form of penicillin that was developed to be resistant to the effects of the enzyme penicillinase, which is produced by certain bacteria. This resistance allows methicillin to be effective against bacteria that have developed resistance to traditional penicillin antibiotics.

This chemical is primarily used as a selective agent in laboratory experiments to isolate and study bacteria that are resistant to methicillin and other related antibiotics. It is commonly used in microbiology research, particularly in studies focused on antibiotic resistance mechanisms and bacterial genetics.

Researchers may utilize Methicillin Sodium Salt in various techniques such as bacterial culture, antibiotic susceptibility testing, and identification of antibiotic resistance genes.
