Can anyone help with MCT1 and 4 quantification on human samples by western blot?

We want to measure MCT1 and 4 on human muscle samples by the use of western blot. On which exact kDa appears the band? Is this a little higher than the expected 42 kDa (eg 49). Information is much...

Contamination of TRIzol by plastic - any thoughts?

We recently put a couple of ML of TRIzol in plastic tubes. RNA extraction afterwards yielded contaminated RNA, indicated by a >2,4 260/280 ratio. Is it possible that the storage of TRIzol in...

Does the time between the making of a home-made (10%) gel and the actual loading of the gel influence the resolution of the bands?

I normally let the gel harden overnight, but is this necessary? Can I, for example, prepare the gel in the morning and load it with proteins in the afternoon?
