I wish to detect cytokine changes in the specific cortex in the rat brain. I am planning to apply IHC+ELISA for localization and quantitative analysis.
Do I need to do PRC or Tissue assay to exam the mRNA level change as well? I was informed Tissue assay is for large quantity. But I am uncertain what "Large quantity" means. I have around 40 rats. Is this large or small?
please feel free to share with me your point of view.
Thanks very much!
