3.親水性AqT?接頭:TFMP基團是高度疏水的,使用傳統(tǒng)的乙烯和乙二醇型接頭用TFMP標記的生物分子傾向于聚集并使標記的蛋白質(zhì)不穩(wěn)定。T2 A14 AqT?連接體通過將兩個蘇糖醇連接在一起制成,大大增加了sxLink?的親水性及其水溶性(2.2 mg/mL飽和溶液)。該分子也具有更好的生物相容性,與其他生物分子的非特異性疏水相互作用降低,允許高載量的苯基二氮雜環(huán)丙烯基團。
2. Reversible disulfide for chemical crosslinking of any biomolecule containing a free thiol.
3. Hydrophilic AqT? linkers: TFMP group is highly hydrophobic, biomolecules labeled with a TFMP using a traditional ethylene and ethylene glycol-type linker tend to aggregate and destabilize the labeled protein. T2A14 AqT? linker is made by linking two threitols together, greatly increasing the hydrophilicity of sxLink? and its water solubility (2.2 mg/mL saturated solution). The molecule is also more biocompatible with decreased non-specific hydrophobic interactions with other biomolecules, allowing high loading of phenyldiazirine groups.
The product is sold as a lyophilized powder in either 1 vial of 250 μg (Cat# CM81401-250UG) or 4 vials of 250 μg (Cat# CM81401-4x250UG). One vial of dissolution buffer is included in each configuration.
