<br>
<br><font size=2 face="sans-serif">you are not writing which primary antibody you use.</font>
<br><font size=2 face="sans-serif">And how you dilute the 0.3 % hydrogen peroxide, in a buffer (like TBS or PBS) or methanol ?</font>
<br><font size=2 face="sans-serif">Just a thought: 0.3 % perox block in buffer for 30 min could be too harsh. The use of methanol, which is no problem in formalin fixed tissue , might destroy the epitope in frozens.</font>
