Abcam has some 'generic' protocols you can use as a starting point; they tend to my first resource for Ab. IHC World as well. I would be glad to help flesh out a protocol if needs be, just need more info as to where you need troubleshooting.
We need to know your protocol to figure out if anything is wrong with it or what could be improved. https://www.thermofisher.com/antibody/product/MAP2-Antibody-Polyclonal/PA1-10005 this antibody worked great for WB and IHC-P, IHC-C, IHC-whole mount.
