[Histonet] autoclave vs. filter of RBC lysis buffer

Sun Jun 4 14:23:49 CDT 2006

I was wondering whether anyone knew why RBC lysis buffer is always filtered and
not autoclaved. Below are the ingredients. I saw some material on the internet
about corrosion of the autoclave, but this was for a different NH4Cl containing
solution. Thanks for any help that you can offer.

4.14g NH4Cl
0.5g KHCO3
0.018g EDTA
dissolve in water
adjust pH to 7.35 with 0.1NaOH
Total volume 500ml

Regards,
Frustrated Scientist

Dear Tim, 
ScyTek in the US do sell bulk reagents for immunohisotchemsitry which are more
or less ready to use. On the other hand you may consider going back to the 'good
old days' where we used to make up the DAB from either from actual DAB powder or
tablets.

Dear Listies,

I would like to start using 250 mL tubs for DAB staining to get staining
time standardized. Is there a source for large purchase of reagents at
an affordable price?

Cheers,

I coat my slides with poly-L-lysine but it seemed that I lost many cells during
the washing steps in IHC. I use a centrifuge my cells onto the slides using the
cytospin. Any idea or comment, Geoff?

My recipe here: http://www.immunoportal.com/index.php Great site: not mine
but I contribute. I must admit that I no longer heat before adding water to
DAB. It dissolves well in RT water.
Hope that's helpful
