[Histonet] RE:Quantum dot IHC

From:"Melissa Gonzalez"

I would suggest diluting further in ranges until you still see the
unspecific background disappear but retain the "real" staining. Also,
ofcourse, make sure the secondary is compatible with the primary
(ie-cross-reactivity between species). 
I am actually curious, you are the first person I have communicated with
that has given Quantum dots a try. What source are you using to
visualize the staining? How do you differentiate the different
wavelengths using these products? I am so happy with Alexa Fluors that I
haven't yet given the Quantum dots a go. 
Good luck, 

Happy New Year to everyone,

Dear Histonet users,

I would like to ask you for advice. I am starting with quantum dot
conjugated secondary antibody immunohistochemistry. I have tried one
with the same protocol I use with Alexa Fluor. Secondary antibody
concentration 1:100 (1:50 is recommended by chemicon), but I have
background. Does anybody have idea what is "best" working dilution?


Thank you very much

Happy New Year
