Hi!! Someone know best method to analyze SUMO1 by western blot? I tried different buffers to extract proteins, different loading buffers, different antibodies and doesnt work :S:S I'm getting mad really, it shouldnt be too difficoult
Thanks so much Bruna, yes I used RIPA buffer suplied with NEM (N-Ethylmaleimide), a specific inhibitor of sumo protease, I used RIPA without it, I used mPER, I used a buffer with urea, I used laemli like loading buffer, I used other loading buffer, I did acrilamide gel with SDS, I used the ab from abcam and I used other ab from CST... and really i dont know what more to do, it doesnt work...what is your positive control?? I want detect endogenous sumo, is not an overexpression.
Hi Bruna sorry to be late, I have not plasmid, I'm just at the begining of this issue, the NEM concentration I used was 50mM like main articles say and yes I diluted it in ethanol. I have no ab SUMO2/3...I just was trying to test a minimal hypothesis to see if is possible to continue in this way or not...so I cant waste a lot of money at first jajaja
