Hello everybody,

 

I'm hoping someone can give me any suggestions on how to detect insulin on a

(paraffin embedded formalin-fixed or frozen) porcine section using the

following antibodies:

 

- primary antibody: Guinea Pig anti-insulin (Dako)

- secondary antibody: Swine anti-Rabbit (Dako)

 

According to the DAKO catalogous the anti-Rabbit should work in this combo.

I have tried it over and over again, using different protocols, but somehow

I just can't get the job done... 

 

Thanks in advance!

It  will  never  work  with   this combination  of  antibodies, what  you
need(and  what  I  use)is a  rabbit  ANTI-GUINEA PIG peroxidase  conjugated,
from  DAKO(P0141) as  your  second  antibody..............

                                                                   Good
luck

would use a biotinylated anti-guinea pig antibody.  I'm not sure if the
anti-rabbit antibody would bind the the GP primary antibody you are using.
I'm pretty sure that Vector sells an anti-GP secondary antibody (I think
they also sell a guinea pig ABC and alk phos kit, depending on the detection
system you are using).

 

Good luck,

es, a biotinylated anti-rabbit IgG does cross-react with guinea pig

antibodies.  I use it all the time when I stain for Insulin, using Dako's

guinea pig anti-Insulin product.

Samatha,
I have had great success with that antibody.
I use it @1:100. I use Goat x Rabbit/Biotinylated @1:100.
I run this on the Ventana but you should get similar results maually.

Poly-HRP goat anti-rabbit IgG would react well with guinea pig primary 

antibody. Kilinipath at Netherlands should be able to help. Klinipath:

Samantha,

 

I had problems years ago using an anti-rabbit secondary.  I'm attaching our
procedure.
