This seem to work for me:

Try to boil your sample in 2X SDS sample buffer with 0.2M DTT, grind the
tissue with a toothpick if necessary, centrifuge away the debree and load
onto the gel.

To determine the protein amount spot dilutions on a PVDF membrane and stain
with coomasie, and destain,  and compare to a known amount of protein
treated in the same fashion
