You have the following reagents available Rat anti-Keratin 8 antibody specific for mouse Keratin 8, Rabbit polyclonal antibody against mouse keratin 5 and antifade reagent with DAPI to stain DNA. Both primary antibodies work best at 1:500 dilution. A) What additional reagents would you need to perform immunostaining of frozen sections of mouse thymus tissue for Keratin 8 that is expressed in cortical thymic epithelial cells and Keratin 5 that is expressed in mouse medullary thymic epithelial cells? B) Create a staining protocol including all tubes and appropriate controls to stain 4 slides with frozen thymic sections. You will need 200ul of antibody staining solution for each slide.
