Sigma Aldrich Fine Chemicals Biosciences p38delta/SAPK4 Protein act
Recombinant GST fusion protein fused to full length human p38delta/SAPK4CHK3
Sigma Aldrich Fine Chemicals Biosciences PyrexR VISTATM graduated c
Single metric scale with blue graduations.
Sigma Aldrich Fine Chemicals Biosciences dCas9 3XfLAGTM Biotin Prot
Recombinant dCas9-3X fLAG-Biotin protein from Streptococcus pyogenes (~165 KD) is a ready-to-use reagent for genome engineering and genomic DNA detection isolation and imaging experiments. When combined with target-specific guide RNAs dead Streptococcus pyogenes Cas9 protein acts as a DNA targeting protein suitable for transfection of cell cultures microinjection DNA pull-down chromatin enrichment microbial identification and in situ DNA imaging. At the C terminus the protein is tagged with a SV40 large T antigen nuclear localization signal (NLS) for nuclear import and both a 3XfLAG epitope and biotin for anti-fLAG(R)-based or streptavidin-based experiments.
Sigma Aldrich Fine Chemicals Biosciences PureColTM Coated 100-mm Di
Collagen is the main structural protein of the extracellular matrix found within various connective tissues of the body. Type I collagen is a major structural component of skin bone tendon and other fibrous connective tissues. In order to provide the most in vivo-like environment for cells researchers have historically cultured cells inside collagen hydrogels or on top of collagen coated plasticware. PureCol(R) is an ultrapure bovine skin derived collagen that is approximately 97% Type I collagen with the remainder being comprised of Type III collagen. It contains a high monomer content as measured by gel permeation chromatography providing product consistency reproducibility and is cited in over 2000 publications. PureCol Coated T25 flasks have a uniform and consistent application of high quality Type I collagen on clear polystyrene surface. The vented flasks have an anti-drip edge and modified canted neck to provide maximum control replacing nutrient depleted media. The flasks h
Sigma Aldrich Fine Chemicals Biosciences Ni SepharoseR High Perform
Ni Sepharose(R) High Performance affinity media for high-reSOLUTIONon high capacity purification of histidine-tagged proteins by immobilized metal ion affinity chromatography (IMAC).Ni Sepharose(R) High Performance consists of highly cross-linked agarose beads to which a chelating group has been coupled. This chelating group is precharged with Ni2 which will selectively retain proteins with exposed histidine groups.The high stability and broad compatibility of Ni Sepharose(R) High Performance maintains biological activity and increases product yield at the same time as it greatly expands the range of suitable operating conditions.
Sigma Aldrich Fine Chemicals Biosciences WilmadR low pressure/vacuu1EA
Novel low pressure/vacuum tube for NMR and EPR spectroscopy. A 4X larger sealing surface eliminates leaks and greatly increases its lifetime when compared to traditional gas-tight tubes. Offers a convenient flame-free sealing SOLUTIONon for air sensitive or volatile liquid samples at any pressure from vacuum to pressure slightly above 1 bar.features Greaseless PTfE piston provides a 100% contamination-free seal. Axial symmetric design guarantees its application in spinning experiments.Economical. reliable CAUTION Due to the nature of glass Extreme Caution should be exercised when using at elevated or reduced pressures as performance of tubes under pressure or vacuum cannot be guaranteed. Adequate safety shielding should always be used when working in these conditions.
Sigma Aldrich Fine Chemicals Biosciences NorellR Select SeriesTM 5
Manufactured out of ASTM Type 1 Class A glass Norell Select Series NMR tubes is specifically designed for high-reSOLUTIONon NMR spectroscopy. The Select Series provides reliable performance for spinning or non-spinning techniques structure determination of small molecules or determining the 3-D structure of a membrane protein.
Sigma Aldrich Fine Chemicals Biosciences PyrexR VISTATM culture tub
These Pyrex Vista culture tubes are supplied with deep-form phenolic caps to facilitate handling and sealing after autoclaving. The blue enamel marking spot gives an excellent surface for pencil notations. Pencil marks are easily erased.
