buffers

Resisting pH changes, buffers protect samples when acids or alkali is added. Powder and liquid forms efficiently track proteins during electrophoresis isolation and separation. The salty buffers can also be used to calibrate and standardize pH meters for accurate readings. Blocking substances stop antibody attachment to membrane free sites that would produce an interfering background. In various concentrations to fit any need, the buffers may come in liquids or dehydrated formats.

I-PER™ Insect Cell Protein Extraction Reagents

Supplier: Thermo Fisher Scientific

The I-PER Insect Cell Protein Extraction Reagent enables gentle and effective extraction of soluble protein from baculovirus-infected insect cells grown in suspension or monolayer culture. The baculovirus insect cell expression system is an efficient and popular system for production of recombinant (eukaryotic) proteins in cell culture. Proteins expressed in baculoviral systems can be used for structural analyses, biochemical assays and a variety of other applications. I-PER Reagent maintains functionality of extracted proteins and is directly compatible with downstream applications such as protein assays, Western blotting and 6xHis-tagged protein purification.
