Project Introduction

泛素化(Ubiquitination)is指泛素 (一类低分子量ofprotein) 分子in一系列特殊ofenzyme作用下, 将cell内ofprotein分类, 从中选出靶protein分子, 并对靶protein进行Specificity修饰of过程. 这些特殊ofenzymeincluding泛素激活enzyme, 结合enzyme, 连结enzymeand降解enzymeetc.. 泛素化inproteinof定位, 代谢, 功能, 调节and降解中都起着十分importantof作用. 同时, 它也参with了cellweeks期, 增殖, 凋亡, 分化,转移, gene表达, 转录调节, 信号传递, 损伤修复, 炎症免疫etc.几乎一切生命活动of调控. 泛素化with肿瘤, 心血管etc.疾病of发病密切相关. 因此, 作for近年来生物化学researchof一pcs重大成果, 它已然成forresearch, develop新药物of新靶点.



技术路线

clientprovide样品经Trypsinenzyme切, enzyme切产物由泛素化Specificityantibody进行泛素化肽of富集, 富集后由高精度质谱analyze, analyze数据由生物信息学软件进行数据检索.

FAQ

    protein泛素化修饰detectneednote以下几pcs方面:

    1. 样品process: 样品processisprotein泛素化修饰detectof关键步骤. in取样, storeandprocess过程中, need避免proteinof损失, 降解and污染. 同时, 要note控制样品ofprocess条件, such as温度, pH值, 离子强度etc., 以确保proteinofstable性and泛素化修饰of保留.

    2. antibody选择: in免疫detect法中, antibodyof选择至关important. need选择Specificity高, 亲and力强ofantibody, 以确保accuratedetect到泛素化修饰ofprotein. 此外, 还neednoteantibodyof来源, batchestimes差异as well asstore条件etc.因素, 以避免影响Experimental Results.

    3. 实验操作: 实验操作过程中neednote细节, such as样品of加样量, antibody稀释度, 反应时间etc.. 这些因素都可能影响Experimental ResultsofAccuracyandreliable性. 因此, need严格按照Experimental Steps进行操作, 并noterecord实验条件and数据.

    4. Result Interpretation: Experimental Resultsneed进行正确of解读andanalyze. neednoteExperimental Resultsof背景值, 信号强度, Specificityetc.方面ofQuestion. 同时, 还need结合实验目ofand背景知识, 对Experimental Results进行合理of解释and推断.

    总之, in进行protein泛素化修饰detect时, neednote样品process, antibody选择, 实验操作as well asResult Interpretationetc.方面ofQuestion, 以确保Experimental ResultsofAccuracyandreliable性. 同时, 还need结合实验目ofand背景知识, 对Experimental Results进行合理of解释and推断.
