U heeft gezocht op: 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.

Catalogus nummer: (PIER28363)
Leverancier: Thermo Fisher Scientific
Omschrijving: Our variety of Pierce Concentrated Buffer stock solutions are ready to use without having to weigh and dissolve dry ingredients or adjust the pH with concentrated acid or base. Simply dilute the liquid stock solution with pure water and proceed with your experiment.
UOM: 1 * 1 L


Catalogus nummer: (PIER89802)
Leverancier: Thermo Fisher Scientific
Omschrijving: 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.

Leverancier: Thermo Fisher Scientific
Omschrijving: The M-PER Mammalian Protein Extraction Reagent is designed to provide highly efficient total protein extraction from cultured mammalian cells.

Leverancier: Thermo Fisher Scientific
Omschrijving: Pierce Protein-free blocking buffer is a non-protein compound that provides effective blocking for membrane-based and plate-based protein detection methods, resulting in extremely low background. It is supplied in a convenient, ready-to-use format.

Leverancier: Thermo Fisher Scientific
Omschrijving: 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.
