A PEGylated derivative of DMG; has been used in combination with other lipids in the formation of LNPs for the delivery of siRNA; LNPs containing C-DMG-mPEG(2000) and encapsulating siRNA targeting the genes encoding PD-L1 and PD-L2 decrease PD-L1 and PD-L2 levels in monocyte-derived dendritic cells
AdipoGen Guanidine thiocyanate
Chemical. CAS 593-84-0. Formula CH5N3 . CHNS. MW 59.07 . 59.09. Guanidine thiocyanate is a powerful, chaotropic agent which is widely used for purification of proteins and nucleic acids. Guanidine thiocyanate is preferred for the purification of RNA because it dissociates the RNA into its nucleic acids and protein forms and is commonly used in the guanidinium thiocyanate-phenol-chloroform extraction method. As one of the strongest protein denaturants, it inactivates nucleases more than twice as fast as Guanidine hydrochloride. It is useful for denaturation and refolding of proteins. At high molarity solutions, Guanidine thiocyanate irreversibly inactivates RNase. Guanidine thiocyanate causes proteins to dissolve readily, thus disintegrating cellular structures.

Medchemexpress LLC Biotin-PEG2-alkyne | 2227450-68-0 | MFCD31922733 | 95.6% | 369.48 g/mol | C17H27N3O4S | 1 G
Biotin-PEG2-alkyne is a short polyethylene glycol (PEG2) linker that bears a biotin group and a terminal alkyne. It is used to biotinylate azide-containing molecules via copper(I)-catalyzed azide-alkyne cycloaddition and for affinity enrichment workflows.
- Enables copper(I)-catalyzed azide-alkyne cycloaddition for click chemistry labeling.
- Provides a biotin tag compatible with streptavidin-based affinity capture and enrichment.
- Short PEG2 spacer minimizes steric hindrance while improving solubility.
- Off-white to light yellow solid, typically supplied with high purity for research use.
- Available in multiple pack sizes to support small-scale labeling and larger preparations.
