Does anyone have any experience with the CD20 rabbit monoclonal antibody
I ordered and received catalog # 1632-1, lot # YD010904. My initial work
up included diluting the ab 1:25 --> 1:200, HIER with Dako Target
Retrieval low pH solution for 20 minutes in a 100 C water bath. Detection
was with Dako Envision + for rabbit antibodies and DAB +. Human tonsil was
used as control tissue. Results: zero, nada, zip, just blue. OK, cranial
flatulence somewhere on my part so I repeated it the next day. Same thing.
Glutton for punishment, I even tried it again.
I called Epitomics and received a replacement... worked it up as above...
same results. Hmmm, guess what? It's the same lot number. At least the
product is consistent.
I called the company again and received a replacement lot # YE042703...
worked it up as above... you guessed it, same results. I don't think I'm
doing anything wrong procedure wise. Has anyone tried a rabbit monoclonal
CD20 from another company or had good results with this one?
