By gradually changing the buffer composition during the run, you can tease apart molecules even more effectively. It’s like a dance party for your molecules, with each one leaving the stage at just the right moment.

Lastly, get ready for the ultimate team-up: gel filtration buddy-buddy with other techniques. It’s the Avengers of molecular analysis! Researchers are combining gel filtration with mass spectrometry or immunoassays, creating powerful alliances that provide even more detailed molecular fingerprints.

So, there you have it, the tantalizing future of gel filtration chromatography. Remember, the world of science is an ever-evolving playground, and this technique is poised to make some noise in the years to come. Stay tuned, my curious friend, for the next chapter in the gel filtration saga!
