【求助/交流】我的蛋白哪去了?焦慮! 已有9人參與
|
| 各位大俠,能否幫我分析一下,我昨天剛剛提取的蛋白,當(dāng)時就加buffer煮沸5min,然后跑電泳,考馬斯亮藍(lán)染色,效果很好,蛋白條帶很清晰,今天想轉(zhuǎn)膜,所以每個樣品都拿出來煮了4min,跑兩個泳道,一個做考馬斯亮藍(lán)染色,另一個轉(zhuǎn)膜(其余操作和昨天一樣)。但是結(jié)果不如人意,和前面的一樣,做考馬斯亮藍(lán)染色后,除了marker以外,沒有其他條帶,轉(zhuǎn)膜的結(jié)果也是這樣,不知道我的蛋白哪去了?大家能否幫我分析一下原因。非常感謝。 |

需要加入蛋白酶抑制劑復(fù)合物,上海生工就有! 本文來自: 小木蟲論壇 http://www.gaoyang168.com/bbs/viewthread.php?tid=2653347 N3-1A Protease Inhibitor Cocktail Series For Protein Extract-----蛋白酶抑制劑復(fù)合物 BS381 Protease Inhibitor Cocktall (For Bacterial Cell, with EDTA) 100X 1ml BBI BS380 Protease Inhibitor Cocktall (For Bacterial Cell, EDTA Free) 100X 1ml BBI BS382 Protease Inhibitor Cocktall (For Fungal/Yeast Cell) 100X 1ml BBI BS384 Protease Inhibitor Cocktall (For Plant Cell) 100X 1ml BBI BS386 Protease Inhibitor Cocktall (For Mammalian Cell) 100X 1ml BBI BS387 Protease Inhibitor Cocktall (For Mammalian Cell) 100X 1ml BBI Component BS380 BS381 BS382 BS384 BS386 BS387 PMSF 100 mM 100 mM 100 mM 200 mM 100 mM 104mM EDTA 100 mM Bestatin 2 mM 2 mM 2mM 1mM Pepstatin A 0.3 mM 0.3 mM 2.2 mM 1mM 1.5mM E-64 0.3 mM 0.3 mM 1.4 mM 1mM 1.4mM 0.1mM 1,10-Phenanthroline 500 mM 500mM Aprotinin 0.08mM 0.08mM 0.08mM Leupeptin 1mM 1mM 0.1mM Price ¥500 ¥540 ¥880 ¥920 ¥1050 ¥160 Description: Crude cell extracts contain a number of endogenous enzymes, such as proteases and phosphatases, which are capable of degrading the proteins present in the extract. The best way to improve the yield of intact proteins is to add inhibitors of these enzymes known to be present in the source material. This series of protease inhibitor cocktail contain a mixture of protease inhibitors with a broad specificity for the inhibition of serine, cysteine, aspartic, metalloproteases, and aminopeptidases etc. which have been optimized and tested for bacterial, fungal /yeast, plant and mammalian cell proteinextraction. Applications:One vial of cocktail is recommend for inhibition of 20g tissues or 109cells in general (BS381 for 4g bacteria). Features:Economical, Ready to use.It is suitable for long term storage. Storage Condition: Cocktail at –20°C.The cocktail is supplied as a clear solution in dimethyl sulfoxide (DMSO), and stable for a year.;Avoid repeated thawing and freezing. |
