We use the bioanalyzer as well for all runs and AmPure for size selection. How do you get the e-gels to work?

Attached is experiment I performed last year comparing E-Gel® SizeSelect™ to PippinPrep (SAGE Science) for the size selection step in Ion LC, prior to library amplification.
SizeSelect Run Conditions:
50 bp DNA Ladder Cat#10416-014
Run SizeSelect™ 2% (program 8)
Time for 185bp DNA target to Reach Reference= 15:04 min
Time for 185bp DNA target to Reach Collection Well= 18:00 minLast edited by lisazgreen; 10-30-2012, 11:35 AM.

I have been using the e-gel for about 4 months now, and have received very consistent library preps from them. Yes, the yield is low nM, but compared to what you need for Ion Torrent Library prep, this is many-fold magnitude more than what you will need for down stream applications. Highly recommend the e-gel for cost, time and reproducibility for NGS library prep.

Do believe it is as simple as you explain. Do you use the elution buffer for e-gels to elute the bands of interest? Any cross-contamination issues with loading?

Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...-

Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...-
