This category covers everyday reagents for molecular and cell biology work. It includes buffers and buffer components such as Tris base, MOPS, CAPS, Bicine, glycine, 0.5 M EDTA solution at pH 8.0 and PBS tablets; detergents including Triton X-100, Tween 20, Tween 80, CHAPS and sodium deoxycholate; bovine serum albumin as Fraction V powder and 20 mg/ml solution; polymers like PEG 1000, PEG 8000 and Ficoll 400; and DNase- and RNase-free molecular biology grade water, along with enzymes, cofactors and amino acids. Pack sizes run from milligrams to kilograms and from milliliters to multi-liter containers.

Check the grade first: molecular biology grade material is tested for nucleases, while ultra pure and reagent grades are defined by each manufacturer's specification. Then compare purity, form (powder, solution or tablet), pack size against how fast you use the material, and storage conditions. Review the SDS before use and request a Certificate of Analysis when you need lot-level records.

Molecular Biology Reagents: common questions

What are life science or biological reagents?

Biological or life science reagents are the chemicals and biological materials used to prepare, grow, separate or analyze cells, proteins and nucleic acids. Examples include buffers, detergents, salts, proteins such as BSA, enzymes, nucleotides and cofactors, and specially purified water. They are graded by purity and testing, which determines whether they suit routine work or sensitive applications.

What does molecular biology grade mean?

Molecular biology grade generally means the material has been tested for, and found free of detectable, DNase, RNase and often protease activity, so it will not degrade DNA, RNA or proteins in your samples. The exact tests vary by manufacturer, so check the specification sheet or Certificate of Analysis for what was tested and the limits used.

What is a lyophilized reagent?

A lyophilized reagent has been freeze-dried: frozen, then dried under vacuum so the water sublimes. The dry product is usually more stable in storage and shipping than a liquid. Before use it is reconstituted with the volume and type of liquid the manufacturer specifies. After reconstitution, follow the stated storage conditions and shelf life.

Can I get pricing for bulk quantities of reagents?

Yes. Volume and quote pricing is available through the Contact Us page, and approved business accounts can pay by purchase order. Chemicals ship only to business addresses, with a company name required at checkout. Many items ship directly from the manufacturer, so lead times vary by item.
