Phenylgalactoside CAS:2818-58-8

Tasirin Ayyukan Enzyme: Ana amfani da Phenylgalactoside akai-akai don auna aikin enzyme β-galactosidase. Lokacin da phenylgalactoside ya sami hydrolyze ta hanyar β-galactosidase, yana fitar da p-nitrophenol. Ana iya auna tarin p-nitrophenol ta hanyar adadi, yana ba da haske game da aikin β-galactosidase. Ana amfani da wannan tasirin a aikace-aikace kamar gwaje-gwajen enzyme da tsarin tantancewa.

Binciken Bayyanar Halitta: Sau da yawa ana amfani da Phenylgalactoside a matsayin wani abu a cikin gwaje-gwajen ilmin halitta don nazarin bayyanar kwayoyin halitta. Kwayoyin halittar lacZ, waɗanda ke ƙunshe da β-galactosidase, galibi ana haɗa su da jerin abubuwan da ke cikin sauran kwayoyin halittar da ke da sha'awa. Bayyanar kwayar halittar lacZ da kuma hydrolysis na phenylgalactoside ta hanyar β-galactosidase na iya nuna yanayin bayyanar da matakin kwayar halittar da ake nazari a kai.

Tsarin tantancewa: Phenylgalactoside muhimmin sashi ne na tsarin tantancewa wanda ke amfani da ayyukan β-galactosidase. Misali ɗaya da aka fi sani shine hanyar tantancewa mai launin shuɗi-fari, wanda ake amfani da shi don gano ƙwayoyin halitta masu sake haɗawa ko waɗanda aka canza a cikin gwaje-gwajen ilimin halittar kwayoyin halitta. Dabbobin da suka yi nasarar ɗaukar DNA mai sake haɗawa ko kuma suka yi haɗin gwiwar kwayoyin halitta za su bayyana β-galactosidase, wanda ke haifar da hydrolysis na phenylgalactoside da kuma samar da launin shuɗi.

Tsarkakewar furotin: A wasu lokuta, ana iya amfani da phenylgalactoside a matsayin ligand don nazarin chromatography na affiliation don tsarkake sunadaran da ke haɗuwa da β-galactosidase ko kuma waɗanda β-galactosidase ke kunnawa. Sunadaran da ake sha'awa na iya samun alamar affiliation ko alamar fusion wanda ke ɗauke da yankin ɗaure β-galactosidase. Ta hanyar wuce cakuda sunadaran ta cikin ginshiƙi tare da phenylgalactoside mara motsi, ana iya riƙe sunadaran da ake so a zaɓi sannan daga baya a cire su.
