[Histonet] Why people are having issues unsubscribing

There are 3 reasons why it is not immediately obvious to people that one of the links at the bottom of Histonet email helps you unsubscribe: 1. In this day and age of internet and email hypertext clutter people simply do not have the time nor the desire to click and explore every link they come

RE: [Histonet] Immunofluorescence

2012-02-07 Thread Leiker, Merced
Paraffin does indeed give a lot of autofluorescence. We use a solution of 0.3% Sudan Black in 70% Ethanol for 10 minutes on the tissues to help with that after the staining. It doesn't mask the autofluorescence completely but reduces it enough to give us good contrast of signal against the

[Histonet] stripping antibodies

2012-01-10 Thread Leiker, Merced
Anyone know a buffer or method (not using heat) to strip antibodies off cells used in an immunocytostaining procedure? The cells are in a multi-well tissue culture dish and have only been labeled with primary (unconjugated) antibody. Thanks. Merced M Leiker Cardiovascular Medicine Biomedical

[Histonet] RE: Using Nail Polish on coverslip?

2012-01-05 Thread Leiker, Merced
I'll seal the coverslip around all the edges and let it dry in the hood for up to half an hour (because of the smell). I use a clear color that doesn't fluoresce under the miscroscope and also allows the slide to be stored at low temp (-20) without the nail polish seal cracking. Also be sure

Do you have access to a confocal microscope or one that does Z-stack imaging? You can find out the thickness of your tissue sections that way (after you've mounted them on a slide of course). Regards, Merced -Original Message- From: histonet-boun...@lists.utsouthwestern.edu

[Histonet] RE: pouring of liquid nitrogen into a cryostat

2011-10-14 Thread Leiker, Merced
I would definitely think it was cause components of the chamber as well as the chamber itself to crack. Liquid nitrogen is MUCH MUCH colder than any temperature your chamber would be, even at its coldest. The temp difference would be too extreme. Just my opinion having a bit of experience

I agree... I've used CD31 to stain tumor vasculature. Some tumor vasculature isn't even lined with endothelium; there's just blood channels. But most should be lined. Regards, Merced -Original Message- From: histonet-boun...@lists.utsouthwestern.edu
