Chemicals Reagents P
Reagents can carry organic and inorganic compounds and classify them as acids, bases, enzymes, or other substances within a lab.
Phosphate Buffered Saline Tablets (PBS) are a balanced salt mixture suitable for various applications, including reagent preparation, flow cytometry, and diluting cells.
Penicillin and streptomycin combination prevent bacterial contamination of cell cultures due to their effective combined action against gram-positive and gram-negative bacteria.
The concentration of streptomycin media can vary depending on the intended laboratory application and the experiment requirements.
