Centrifuge after lysing - (Jan/23/2010 )

I have seen in many protocols what samples will be centrifuged after they are lysed. What is the purpose of this? I can't seem to find the answer anywhere!


to pull down the chunks of un-dissolved and insoluble material left behind from the cells lysing. If left in suspension, it will make aliquoting and pipetting of your samples difficult.

Good to see your grasp on the finer points of technical language is still up there, bob :D :lol:



Just trying to be the common person these days ;)


hi, i use a very strong sds to lyse my cells and i usually do not centrifuge. and it works well as my target proteins is inside the nucleus. Any account for that?


IF it works, then there probably isn't a problem. You may find that your cultures have a few lumps of stuff in them occasionally that makes pipetting hard.
