Molecular Biology Reagents/Chemicals
MIDSCI™ gives you ultra-pure, cost-competitive molecular biology reagents and lab chemicals for life science research; often with significant cost savings over Sigma Aldrich and other lab reagent providers.
PR1MA™ Chemicals can help with a wide variety of research-based requirements.
Use our glycerol for polyacrylamide gel electrophoresis. Eliminate Agrobacterium after inoculation with the carbenicillin we carry. Or detect β-Galactosidase activity with X-GAL which, when combined with the IPTG we stock, can be used to detect lac gene expression in cloning applications.
We also carry Luria Broth (Lennox), for the propagation and maintenance of E. coli; DTT, in order to maintain –SH groups in a reduced state; and high gel strength agar for tissue culture and microbiological work.

PR1MA™ PBS [Phosphate Buffered Saline]
Common Name: Phosphate Buffered Saline
CAS Number: 7647-14-5; 7447-40-7; 7558-79-4; 7778-77-0
Solubility: Water
Storage Temp: Room Temperature
PBS, 100 mL Tablets refer to pre-weighed tablets that are used to prepare a specific volume of PBS (Phosphate Buffered Saline) solution.
PBS is a widely used buffer solution in biological and biochemical research. PBS serves as a versatile buffer for various applications, including cell culture, immunohistochemistry, protein and nucleic acid research, and diagnostic assays. It helps maintain a stable pH and osmolarity, providing optimal conditions for biological reactions and preserving the integrity of cells and biomolecules.
Each tablet contains pre-determined amounts of sodium chloride, sodium phosphate dibasic, and potassium phosphate monobasic. When dissolved in distilled water or a suitable solvent, the tablet dissolves, releasing the components, and instantly forms a ready-to-use PBS solution with a total volume of 100 mL.
These tablets ensure accurate and consistent preparation of PBS, eliminating the need for weighing and measuring individual components. They are designed to simplify the process and save time in laboratory workflows.
Research or further manufacturing use only, not for food or drug use.
