Description:
Azide/azido functionalized polyethylene glycol (N3-PEG-X) is a bifunctional PEG derivative that can be used to modify proteins, peptides and other materials. Azide group can react with alkyne in aqueous solution catalyzed by copper. It can also be reduced into amine group easily while another functional group can be react with other molecules or functional groups. 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.
Description:
Amino functionalized polyethylene glycol (NH2-PEG-NH2) is a homobifunctional PEG derivative that can be used to modify proteins, peptides and other materials via carboxylic group (-COOH) or other amine reactive chemical groups. 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.
Description:
Petroleum ethers are low boiling aliphatic fractions, which are derived from crude petroleum via fractional distillation. The boiling range is 40 to 60 °C, which gives a high evaporation rate. Suitable for GC and Pesticide Residue Analysis.
