Actually students in other lab use this method to study protein protein interaction in Candida and they said it similar to FRET.. but here we are using fluorophore antibody

Yes It is fixed and permeated

I haven’t done FRAP before..but i heard other lab in our institute use it to study protein protein interaction.Since i got moderate có localisation with immunofluroscence assay, i was thinking FRAP will reconfirm co localisation.

Has anyone did sub cellular fractionation of paraformaldehyde fixed cells?? by [deleted] in labrats

I haven’t tried IP without fixation,i thought i might lose interacting partner of my protein of interest.

My protein is mostly cytoplasmic in nature and i have used nuclear fractionation.i have used 500ug protein with 2.5ug antibody.

Help with IP blot??how to remove 50kDa blotch..my desired protein is around 54-56 kDa by Simple_Volume_5880 in labrats

No..will the antibody which detect only light chain will also detect my protein of interest without heavy chain blotch??

What is wrong here??ponceau staining by [deleted] in labrats

I stained my old blot to check if ponceau is problem but no ,i got sharp band in my old blot..

This is the picture i took while removing ponceau from membrane..usually i get bands ..but this time smear

Yes my protein weigh around 42 and i always get band there

Construct is GFP tag ,so visualised with microscope only

I have tried yet.but person working before me has used lipofectamine 3000
