I am going to look at my patch-clamped neuron which received Neurobiotin tracer (SP-1120) in the sections using streptavidin, Alexa Fluor 568 conjugated dye. Any tips or thoughts will be appreciated.
And Great thanks for your valuable tips and comments, I appreciate them a lot! :-)
I have looked at a sample (it was developed for clarity technique) yesterday, and notice a high autofluorescence and background staining. It was looking that I stained all other neurons too, which I didn't!
Now, I am going to do the usual IHC technique for 30um thick brain sections, and the only marker I am using is Alexa 568 streptavidin for marking Neurobiotin in the single patched neuron.
I was wondering if you have noticed such an effect (high fluorescence unspecified background) in your samples too?
Again, very grateful for the valuable time which you spent helping me, and the experiences which you shared with me.
I have just noticed in the protocol you kindly send me, you are using 1:1000 Alexa568-streptavidin (I am using 1:500 like Martina), only for 60 min and not over the night, right?
I am going to use IHC protocol so:
1. Rinse the sections (30 um) with KPBS 3x10 min.
2. Incubate overnight with KPBS, 1% BSA (Bovine Serum albumin), Triton-X, and Streptavidin conjugated with Alexa 568-streptavidin (1:500), @ +4C.
