What are the limitations of blotting techniques and what
alternatives can you suggest?

Answer Posted / 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:
