His-Tag specific labeling for MST using RED-tris-NTA

The reagents for sample preparation have an important impact on the outcome of the measurement. In modern instrumental trace analysis, any impurity can disturb the measurement so acids with low impurities should be used to minimize the interference on the instrument signal. High purity Suprapur ® acids offer the most suitable purity of wet digestion materials with low impurities during the entire minimum shelf life.

Visualize and quantify the total protein content on Western blot membranes with Revert 700 Total Protein Stain. Revert 700 Total Protein Stain provides linear, proportional signal across a broad range of sample concentrations.

Intercept T20 Antibody Diluents for use with Odyssey® Imaging Systems, are optimized for use with IRDye® Infrared Dye Reagents and other near-infrared fluorophores.

IRDye and VRDye secondary antibodies are highly cross-adsorbed, making them suitable for multi-color detection. IRDye secondary antibodies have been optimized for use with the Odyssey® family of imaging systems and can be used on instruments with similar excitation and emission filters.

Try Intercept (TBS) Blocking Buffer or Intercept (PBS) Blocking Buffer for improved results in your quantitative Western blots and other immunoassays. Intercept Blocking Buffers provide excellent blocking performance with low background and low variability.  

Redox standard (with Ag/AgCl/c(KCl)=3 mol/L reference electrode gives U = 250 +/-5 mV (20° C); can also be used as buffer pH=7)

The scientists at 21st Century Biochemicals have decades of peptide synthesis and purification experience. We manufacture 100% of the peptides we sell in our laboratories in the Boston area. Unlike most other peptides companies that produce peptides off-shore or purchase peptides from 3rd parties, we control all aspects of the manufacturing process and thus you can be assured that your peptides will be of the highest quality.…

The organics are those compounds which are gaseous, liquid, or solid chemical and whose molecules contain carbon. Unlike most other elements, carbon forms strong bonds to other carbon atoms and to a wide variety of other elements, including hydrogen (most compounds contain at least one carbon-hydrogen bond). The organics include pharmaceuticals, medicines, plastics, paints, and fibers. In addition, DNA, peptides, proteins,…
