R-PE抗體標誌套組
只需一個步驟
不須Dialysis或desalt步驟。效能近乎100%。
(貨號#703-0010)
R-Phycoerythrin (R-PE)抗體標誌directly labeling kit (貨號#703-0010),一定選擇英國innova biosciences公司專利研發之lightning-link套組。市面上antibody labeling kit,在pH8~9環境下做反應。如此地環境易造成抗體活性失效,即使照著原廠提供的Protocol下進行反應,抗體回收的效能也很差。因為多太抗體未被標誌,必須移去未結合的抗體。如此浪費珍貴的抗體。
英國INNOVA BIOSCIENCES,以生物結合為主要事業。於1996年專利研發,中性環境下進行抗體結合反應,只要一個步驟,30秒hands on time。其抗體回收效能近似100%。不須再做Dialysis或desalt的步驟。
Lightning-Link 只要一個步驟,即可將蛋白質/抗體/胜肽做標誌,具專利研發Quencher reagent化學反應徹底中止殘餘反應及停止非專一性結合,因此無須desalt及dialysis,抗體標誌回收率100%。
Lightning-link抗體標誌原理:
Lightning-Link以共價鍵結,辨視amino groups,性質極為穩定,一次反應後,可冷凍保存,節省實驗時間。
R-PE螢光蛋白特性
R-Phycoerythrin (R-PE) is a fluorescent protein from the phycobiliprotein family,
and is isolated from red algae. The absorbance spectrum of R-PE covers a broad
range of excitation wavelengths, which provides an advantage for multi-color
immunofluorescent staining or cell sorting. R-PE is one of the most intensely
fluorescent phycobiliprotein having orange fluorescence. It is significantly brighter
and more photostable than conventional organic fluorophores and it has a high
quantum yield.
Absorbance
Max (nm)535
Emission
Max (nm)575
Lightning-link抗體標誌V.S.保存液:
抗體保存於Azide、Gelatin及BSA溶液下,會干擾一般結合的效果,所以會再經過純化步驟,浪費許多抗體。Lightning-Link克服Azide、Gelatin及BSA干擾結合的效率,省下您寶貴的抗體。別於其它結合的方式,Lightning-Link無須在High pH的溶液下操作,所以只要是具有amino groups (lysin/a-amino)的蛋白質/胜肽/抗體,都可反應。
Lightning-link抗體標誌應用:
可以應用在ELISA. immunofluorescent. Flow. confocol. Western Blot等檢診及分子病毒之研究!!直接在一抗上做標誌 (可標誌螢光蛋白 螢光dye HRP Biotin等) 只要一個步驟 回收100%。這個方法克服二抗所造成的背景值過高及Host來源不同所造成Crosstalk的現象.
