Description:

Nanocs provides various functionalized superparamagnetic particles that can be used for biomolecule separation, imaging and diagnostic application. Our small sized paramagnetic nanoparticles, with diameter in 25~50 nm, are suitable for fluorescent imaging, cellular and biomolecular labeling and magnetic sensing. Because of their small size, this type of magnetic nanoparticles cannot extracted with regular magnets. Our large size magnetic particles, with diameter 250 nm or above, can be exacted with magnets and therefore, can be used for cellular and biomolecule separation. Customer conjugation and modification is available upon request.

Physical Properties:

  • 1% suspension in aqueous solution, other concentration available upon request;
  • Brownish or dark brown solution;

Storage Conditions:

  • Store at 4 0C. Do not freeze.

Tetrazine PEG Derivatives

Description:

Tetrazine PEG derivatives are used to react with TCO (transcyclooctene) groups. The reaction of tetrazine and TCO is a bioorthogaonal reaction that enables the conjugation of two molecules in aqueous solution fast and efficiently. Tetrazine PEG derivatives have excellent water solubility, possess fast kinetics and stability in aqueous buffer. They are one of the best pegylation reagents to modify proteins, peptides, antibodies, biopolymers and particles via copper free Click Chemistry reaction.

Product Specifications:

  • Appearance: White solid;
  • Solubility: Soluble in water, ethanol, DMSO, etc.;
  • Reactivity: Tetrazine reacts with TCO.

Storage:

  • Store at -20 0C; Desiccate; Avoid frequent thaw and freeze.

Description:

Boc-NH-PEG-COOH (Boc PEG acid) is  one of Nanocs heterobifunctional PEG derivatives that can be used to modify proteins, peptides and other materials via amino or other acid reactive chemical groups. Boc group can be de-protected under acidic conditions to release free amine for further reaction. PEGylation can increase solubility and stability and reduce immunogenicity of peptides and proteins. It can also suppress the non-specific binding of charged molecules to the modified surfaces.

Physical Properties:

  • Form: Solid
  • Color: White
  • Solubility: Soluble in water, chloroform
  • Purity: >95%

Storage Conditions:

  • Store at -20 0C. Protect from light. Avoid frequent thaw and freeze.

Description:

1,2-Distearoyl-sn-Glycero-3-Phosphoethanolamine (DSPE) and PDP conjugated Polyethylene Glycol is a heterobifunctional PEG derivative that can undergo reaction with sulfhydryl group. DSPE PEG is an 18 carbon phospholipid PEG conjugate which has both hydrophilicity and hydrophobility. PDP (pyridyldithiol propionate) is reactive toward free thiol group to form cleavable disulfide bond. Pegylated phospholipids are excellent liposome formation materials that can be used for drug delivery, gene transfection and vaccine delivery as well. Pegylation of phospholipids significantly improves the blood circulation time and stability for encapsulated drugs. These materials can also be used for targeted drug delivery by modifying their surfaces with targeting ligands such as antibodies, peptides.

Physical Properties:

  • Off-white/white solid or viscous liquid depends on molecule weight;
  • Soluble in warm aqeous solution as well as most organic solvents;

Storage Conditions:

  • Store at -20 0C, dessiccated Protect from light. Avoid frequent thaw and freeze.
