at first, I am still a beginner in siRNA experiments, this is my first one
I want to silence specific two genes
I bought siRNA from sante cruz company.
with all kit, like transfecting agent, medium and control siRNA.
and I cultured my cells and followed the protocol as written exactly,
after finishing the experiment and waiting 24 hrs, I wanted to test the presence of this protein in the cell i silenced, so I stained my cells by immunofluorescnece.
However, I could not see any difference, between, control siRNA and gene silenced and even normal cells.
so I tried again, with 2 experiment, 1 changing the transfection reagent into RNAi fect, and 2- repeat the same old experiment but waited for both exp longer time, perhaps my protein half life time is long (65 hrs)
however, today, I can see the same under microscope.
for both genes I used.
I know that I need rt-PCR or western blot to prove silencing of specific gene.
The use of immunofluorescence staining is good way to prove silence gene?
Do u have any suggestion for my to think about since I am beginner?
Do u have any experience regarding this company and siRNA products
at the end, I am very grateful for those who is welling to share their experience with me
