can i use old blood - (Feb/26/2014 )

dear:all

can i use blood after 24hr.preservation in refrigerator for intracellular and surface staining in flow?

 

if i used frozen BPMCS in intracellular staining what is the precaution specific for flowcytometry after thawing?and should use immediatly after thawing ?can i transport cells in ice books for 15 min.?

 

kind regard

Not sure. But what if some of cells disrupt? it would produce background noise!!!

is this for both questions or the 1st only?

Generally cells should be thawed quickly. As to your last question, transporting on ice should not be a problem.

I just typed     pbmc flow cytometry thawing     into google and got some interesting results and protocols, such as:

and a lot more...Maybe you shoud just read some of them. Hope it helps :)

1st. Disrupted cells could come outside staining medium (Sheath fluid or whatever).

See above links by Tabaluga. Need to follows correct freeze - thaw protocol. 

 

These protocols are for PBMC. In first question when you mention blood, you mean PBMC right?
