生物素-親和素相互作用通常用于檢測(cè)和/或純化蛋白質(zhì)服務延伸，因?yàn)檫@兩種分子彼此具有高度特異性堅持好。生物素化是將生物素附著在蛋白質(zhì)和其他大分子上的過(guò)程大數據。

在選擇生物素化試劑時(shí)密度增加，用戶需要考慮以下幾個(gè)方面單產提升。

The biotin–avidin interaction is commonly exploited to detect and/or purify proteins because of the high specificity that these two molecules have for each other. Biotinylation is the process of attaching biotin to proteins and other macromolecules.

When selecting the biotinylating reagents, the user need consider the following aspects.

BroadPharm has all kinds of biotinlyation reagents for meet the need of your advanced research. The variability of these reagents substantially expands the range of applications for avidin–biotin chemistry

• *Varieties of biotin functional group reagents differ in length, solubility, cell permeability and cleavability.

• *Varieties containing disulfide bonds can be cleaved using reducing agents, enabling the biotin group to be disconnected from the labeled protein.

• *Non-sulfonated NHS-biotins are cell permeable but must be dissolved in organic solvent such as DMSO or DMF.

• *Sulfo-NHS biotins (and those with pegylated spacers) are directly water soluble but not membrane permeable.

BroadPharm擁有各種生物素化試劑數字化，以滿足您高級(jí)研究的需求全面協議。這些試劑的可變性大大擴(kuò)展了親和素-生物素化學(xué)的應(yīng)用范圍

*各種生物素官能團(tuán)試劑的長(zhǎng)度創造、溶解度的方法、細(xì)胞通透性和裂解性各不相同實事求是。

*含有二硫鍵的品種可以使用還原劑進(jìn)行裂解，使生物素基團(tuán)能夠與標(biāo)記的蛋白質(zhì)斷開(kāi)落到實處。

*非磺化NHS-生物素具有細(xì)胞滲透性服務水平，但必須溶解在有機(jī)溶劑中，如DMSO或DMF技術創新。

*Sulfo-NHS生物素（以及那些帶有聚乙二醇化間隔物的生物素）是直接水溶性的處理方法，但不能滲透膜。
