The major limitation of blotting procedures is the length
of time needed and the fact that they can accommodate only
one probe at a time.

Answer / abe
Blotting techniques show many limitations in comparison to other molecular techniques. It depends what you're attempting to look for, it's very situational.
- They take up alot of time
- They degrade protein tertiary structure
- They show limited quantitative abilities
- They show lower specificity and sensitivity compared to other techniques.
If you're looking for gene expression I would say reverse-transcriptase PCR is a more appropriate alternative.
Here is a good article discussing these limitations:
