Re: E-Cadherin

From:Noel Moon <>

I use Cell Marque's E-Cadherin in the prediluted form and have excellent 
luck with it!  Maybe you could leave it on for a longer time period and 
titer it out alot?  If it was something that you could incubate overnight in 
a humidifier chamber, then I bet you could get 1:100 from it...just a 
thought.  I know that there are a couple of low-titer abs that I dilute 
heavily and leave overnight and run them as usual when I get in in the 
morning. If money is an issue, then you may have to consider this for a 
quality antibody.  The folks at Cell Marque are great to my lab...always 
helpful and willing to work with me. They are my primary antibody 
vendor...with the exception of a couple, but that's only because they don't 
carry those.  Incidentally, I was looking for a monoclonal kappa and lambda 
and they had it all along (thanks Laura!)

Thanks to all you histonetters for giving a helping hand.

Happy Cinco de Mayo!!!! I'm not even Latino, but I love those margaritas!
