SCIEX Low pH SDS Sample Buffer, 140 mL (100 mM Tris-HCl, pH 6.8, 1% SDS) allows you to use SCIEX’s Gold Standard CE-SDS with a low pH SDS sample buffer. Use of this buffer can increase non-reduced purity by decreasing method induced fragmentation. Less variability and lower RSDs means less troubleshooting and faster method development.

HyClone AdvanceSTEM ES Qualified HEPES provides maintenance of physiological pH in cell culture despite changes in carbon dioxide.

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.

Role of a balanced salt solution in cell culture is multifaceted and can be divided into four principal functions:

Supplier: Thermo Fisher Scientific

The NE-PER Nuclear and Cytoplasmic Extraction Kit provides for efficient cell lysis and extraction of separate cytoplasmic and nuclear protein fractions in less than two hours. The nuclear protein extraction method involves simple, stepwise lysis of cells and centrifugal isolation of nuclear and cytoplasmic protein fractions. A benchtop microcentrifuge, tubes and pipettors are the only tools required. The NE-PER Reagents efficiently solubilise and separate cytoplasmic and nuclear proteins into fractions with minimal cross-contamination or interference from genomic DNA and mRNA. The isolated proteins can be used to perform immunoassays as well as protein interaction studies such as mobility shift assays (EMSA), co-immunoprecipitation (Co-IP) and pull-down assays.
