Has anyone used AMPureXP beads older than 18 months, (assuming that they were stored properly)?

Hi there,
Off the top of my head I think I am using a bottle, stored at +4, that is currently sitting older than 18 months and they have performed perfectly in all my recent preps so I'd say you're good to go! -
I used AmpPure beads ~ + 4 month. They have worked. I have checked mine first with a not important sample. You can test yours with a DNA ladder. I think it is in general a good idea.Comment

I have sometimes used Ampure beads that were 1-3 years past expiration date. They sort of work, but they seem to become less magnetic and and are therefore more difficult to work with.Comment

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...04-04-2024, 04:25 PM -
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...03-22-2024, 06:39 AM
