Kyfora Bio DSPE 25 MG
DSPE (1,2-Distearoyl-rac-glycero-3-Phosphatidylethanolamine) is a saturated zwitterionic phospholipid and a derivative of phosphatidylethanolamine. It can be used in liposomal drug and gene delivery formulations. DSPE can be conjugated with PEG or PCB to develop stealth liposomes that have extended circulation time in the bloodstream.Key application(s): LNP, stealth liposomes
LAYSAN BIO INC Maleimide-PEG-Succinimidyl Valarate (MAL-PEG-SVA) molecular weight: 5,000., 500mg
Maleimide-PEG-SVA (Succinimidyl Valerate) is a heterobifunctional combining a maleimide group at one end of the PEG chain and a succinimidyl valerate group at the other. This unique structure allows it to react with both thiol (-SH) and amine (-NH2) groups, making it highly versatile for various bioconjugation applications.

Gold Biotechnology Inc Proteinase K, RNase/DNase free 1 g
Proteinase K is a highly reactive nonspecific serine protease that belongs to the subtilisin family of proteins. It cleaves at the carboxylic acid side of aliphatic, aromatic, or hydrophobic amino acids. Proteinase K is capable of inactivating RNases and DNases and is used in the isolation or preparation of high molecular weight nucleic acids. Proteinase K is also useful for helping to characterize enzymes, due to its cleavage specificity. This enzyme was designated proteinase K because of its ability to hydrolyze keratin. Proteinase K is stable in a wide variety of detergents and buffer salts and at various temperatures and pH. The isoelectric point of proteinase K is 8.9.
Gold Biotechnology Inc DTT (Dithiothreitol) (> 99% pure) Protease free 25 g
Dithiothreitol (DTT) is the common name of the more popular of the two Cleland’s Reagents (the other being Dithioerythritol or DTE). DTT is a powerful reducing agent that forms a stable six-membered ring with an internal disulfide bond which is resistant to oxidation. DTT is often used for the following: reducing the disulfide bridge of the cross-linker N,N′-bis(acryloyl) cystamine to break apart the matrix of a polyacrylamide gel, the reduction of disulfide bonds in proteins, the prevention of those bonds from forming between cysteine residues and lastly, DTT is often used to reduce thiolated DNA in order to minimize dimerization.
