Sigma Aldrich Fine Chemicals Biosciences HiTrapR Heparin High Perfo
HiTrap(R) Heparin HP columns are prepacked with Heparin Sepharose(R) High Performance for high-reSOLUTIONon purification of proteins withaffnity for heparinsuch as DNA-binding proteins coagulation factors lipoproteins and protein synthesis factors.Immobilized heparin has two main modes of interaction with proteins. It can operate as an affinity ligand with affinity for a wide range of biomolecules including coagulation factors and other plasma proteins lipoproteins protein synthesis factors enzymes that act on nucleic acids and steroid receptors. Heparin also functions as a high capacity cation exchanger due to its anionic sulfate groups. Gradient elution with salt is most commonly used in both cases.Heparin is coupled to the Sepharose(R) High Performance base matrix via the N-hydroxysuccinamide coupling method to give high capacity performance and low leakage levels. HiTrap(R) Heparin HP is delivered in 0.2 M NaCl with 20% ethanol as bacteriostatic agent. Store HiTrap(R) H
Sigma Aldrich Fine Chemicals Biosciences Ten Eleven Translocase TET
This product consists of the catalytic domain (CD) of mTET1 (amino acids 1366-2039) and includes an N-terminal polyhistidine tag. It has a calculated molecular mass of 75.8 kDa. This protein is produced in mammalian cells (HEK 293) without the use of serum. The mammalian cells expression system allows proper post-translational modifications and folding and often supports higher specific activity of the protein.
Sigma Aldrich Fine Chemicals Biosciences PD Miditrap G 25 Cytiva 28
PD MidiTrap(TM) G-25 is a prepacked single-use column for buffer exchange and cleanup of biological samples for example proteins and carbohydrates.
Sigma Aldrich Fine Chemicals Biosciences Lipopolysaccharide from Po1MG
Lipopolysaccharides (LPSs) are characteristic components of the cell wall of Gram-negative bacteria. LPS and its lipid A moiety stimulate cells of the innate immune system by the Toll-like receptor 4 (TLR4) a member of the Toll-like receptor protein family which recognizes common pathogen-associated molecular-patterns (PAMPs).
