產(chǎn)品詳情
相比近年來有長足進展的生物樣品純化和晶體X射線衍射技術(shù),生物大分子晶體的培養(yǎng)依然是一個試驗探索的過程,極大程度地依賴于經(jīng)驗并帶有較大的盲目性。 蛋白結(jié)晶所需的各種成分,如沉淀劑、鹽、緩沖液體系、有機溶劑以及各種添加劑,構(gòu)成一個龐大的多維集合。雖然現(xiàn)在市場上有一些商業(yè)化的晶體生長條件篩選盒,但它們只能構(gòu)成一個一個獨立的小子集, 遠遠無法覆蓋非常復雜、巨大的蛋白結(jié)晶條件集合。
博亞的BioXtal™結(jié)晶條件篩選盒是為蛋白晶體生長條件篩選而特別開發(fā)的一個晶體生長條件組合。 其成分組成是以大量發(fā)表和未發(fā)表的結(jié)晶統(tǒng)計數(shù)據(jù)為基礎發(fā)展而成。它既包含離散矩陣篩選模式也包括系統(tǒng)性篩選模式,既含*效的結(jié)晶條件也含許多其它結(jié)晶條件篩選盒所未有的條件。 擴展了篩選范圍從而增大了發(fā)現(xiàn)結(jié)晶條件的幾率。
該試劑盒有96個條件以適合96孔板自動化篩選設備,pH范圍涵蓋蛋白晶體最易生長范圍4.5-8.5。所使用的化學試劑來自國標*化學試劑公司(Fluka、Sigma-Aldrich等),并且每種溶液都經(jīng)過0.22μ慮膜過慮滅菌處理。96個條件分別密封在螺旋蓋試管中,每管不少于10毫升,可隨便使用。
在最近進行的大量蛋白晶體篩選測試研究中,博亞BioXtal™結(jié)晶條件篩選盒曾結(jié)晶出了超過50%的可結(jié)晶蛋白。被認為是高效結(jié)晶條件組合,是一個對現(xiàn)有商業(yè)化的結(jié)晶條件篩選盒的有力補充和發(fā)展。
