Sep 02, 2021 · Sample filtration has been shown to be an important tool for improving the results from LC-MS. In part 1 of this two-part blog series, we review the results of some recent studies that looked at the improvements made possible by sample filtration with syringe filters prior to HPLC, and how to obtain these improvements without introducing other unwanted errors and effects.

Jan 26, 2017 · 1. Introduction. The discovery of exosomes dates back to 1983 in two independent papers published respectively by Harding et al. 1 and Pan et al., 2 and later confirmed by Pan et al. 3 In these papers, the authors cultured immature red blood cells - reticulocytes with labeled transferrin receptors to trace the movement of transferrin receptors from plasma membranes into the reticulocytes.

(Larissa, Greece), ELISA AgraQuant Aflatoxin M1 High Sensitivity Assay 5/100 by Romer Labs Singapore Pte Ltd. (Jalan Bukit Merah, Singapore), and ELISA RIDASCREEN Aflatoxin M1 by r-biopharm (Darmstadt, Germany).
This short animation explains how your syringe filter might be putting your HPLC at risk. Some syringe filters exhibit unpredictable loss of membrane integrity, allowing particles to pass through the filter. These particles could contaminate and/or clog the expensive HPLC column.
