4-ARMPEG MAL (plaub caj npab Polyethylene Glycol Maleimide)

4-ARMPEG MAL (plaub tub rog polyethylene glycol maleimide) yog ib qho kev sib txuas ntawm ntau yam riam phom, nrog rau pawg txiv neej txuas nrog cov tub ntxhais pentaerythritol ntawm txhua qhov kawg ntawm plaub caj npab, uas tuaj yeem xaiv ua haujlwm nrog mercaptan pawg ntawm 5.{{2 }}.5 ntawm pH. Cov pab pawg Maleimide hnov ​​​​qab xaiv nrog dawb sulfhydryl, SH, sulfhydryl lossis sulfhydryl pawg los ntawm Michael ntxiv kom tsim cov pa roj carbon sulfur ruaj khov. 4-armpeg-mall tuaj yeem siv rau qhov chaw tshwj xeeb protein thiab peptide hloov kho. Raws li ib tug txiv neej derivative, 4-armpeg mal tuaj yeem txuas mus rau PEG hydrogels.

PEG hydrogels muaj ntau daim ntawv thov hauv cov khoom siv kho mob thiab cov tshuaj kho dua tshiab, thiab tseem ceeb heev rau kev tshawb fawb, tshwj xeeb tshaj yog rau kev tswj cov tshuaj, 2D thiab 3D kab lis kev cai ntawm tes, qhov txhab sealing thiab kho.
