产品介绍：
PEI 40000是一种分子量为40000的高电荷阳离子聚合物，非常容易结合带负电荷的核酸分子，形成复合物，并使该复合物进入细胞中。PEI 40000是一种瞬时转染试剂，细胞毒性低，转染效率高，在HEK293和CHO等细胞中基因表达效率较高。目前已经验证线性PEI转染试剂广泛适用于多种细胞系包括HEK-293、HEK293T、CHO-K1、COS-1、COS-7、NIH/3T3、Sf9、HepG2和Hela细胞等，转染效率高达80%~90%。
PEI 40000与PEI 25000转染试剂相比，具有很多优点，具体表现在以下几个方面：
1. PEI 40000较易溶解，可直接在水中溶解，PEI 25000需要先把水调成弱酸性助其溶解，溶解后再用NaOH把pH调至中性；
2. PEI 40000操作简便，更易于使用，且比PEI 25000的转染效果好；
3. PEI 25000含有4-11%的丙酰基残留，其能阻止聚合物主链与DNA结合。相较于PEI 25000，PEI 40000是wan全脱落的结构，因此其性能始终高效如一。本产品为速溶型，溶解迅速，配制方便。

DSPE PEG NHS, MW 5000 Cat. No. PG2-DSNS-5k-2 500 mg修饰性聚乙二醇

DSPE-PEG-NHS, MW 5000, 500 mg
Synonym: 1,2-Distearoyl-sn-Glycero-3-Phosphoethanolamine PEG NHS, NHS PEG DSPE, DSPE PEG Succinimidyl ester
DSPE PEG NHS is one of Nanocs reactive phospholipid PEG conjugates that can react with primary amine groups. DSPE (1,2-distearoyl-sn-glycero-3-phosphoethanolamine) is an 18 carbon phospholipid that is highly hydrophobic. PEG backbone, on the other hand, offers good hydrophilicity and water solubility. Succinimidyl ester (NHS) on the other PEG terminal reacts with primary amine groups efficiently at pH 8~10. NHS PEG DSPE thus can be easily incorporated into liposome and other nanoparticles via the reaction of NHS and amine. DSPE PEG NHS is one of most commonly used reactive phospholipids to conjugate antibodies, proteins, peptides or other substrates to the surface of liposome and other lipid PEG nanoparticles. Pegylated phospholipids have longer blood circulation time and higher stability for encapsulated molecules. Nanocs has developed a comprehensive collection of chemical reactive phospholipid PEG products that have high purity, various molecular weights and excellent chemical reactivity. These lipid PEG conjugates demonstrate excellent amphilphilic properties and offer superior advantages for small and large molecule modification, formulation and delivery.

mPEG Desthiobiotin, MW 5000
|
Synonym: mPEG Desthiobiotin, Desthiobiotin PEG, Desthiobiotin PEG5000, DSB PEG
mPEG Desthiobiotin is one of Nanocs’ pegylated desthiobiotin PEG derivatives that is soluble in water. Desthiobiotin is a modified version of biotin. Compared to biotin, desthiobiotin binds to streptavidin, avidin and other biotin-binding proteins with lower affinity and it can be eluted from binding complex under much milder conditions (i.e., by competitive displacement with regular, free biotin). As such, desthiobiotin reagent is a useful alternative to Biotin for avidin-biotin techniques in which nondenaturing elution of the labeled proteins is desired. Pegylated desthiobiotin has good solubility and can be easily used in biotin/streptavidin assays and biomolecule purification process.
Physical Properties:
- Off-white/white solid;
- Soluble in water;
- Binding group: Desthiobiotin;
- Bind to: Streptavidin;
- PEG type: PEG5000, linear;
Storage Conditions:
- Store at -20 0C. Desiccate. Avoid frequent thaw and freeze.
