Loss the contact closure signal
our 7600 couple with nanoLC Ultimate 3000 via contact closure. it has run without any loss connection during the batch. Just yesterday, the last injection keep equilibrating system until the LC finished the gradient run. We closed the software and power off LC and MS then started again but it did not help. The Dionex engineer also checked their LC and triggerring cable found both are ok.

Full, partial and empty capsid ratios for AAV analysis: What’s the big deal?
For many of you working to develop gene therapy drugs, you know that the time to market the drug is critical. Because gene therapeutics cure diseases by targeting specific genes, it is a constant race to see who develops the drug first. Unlike other classes of drugs where multiple medications can be used to treat a disease, whoever is first to develop a gene therapy drug wins.

A rising star in food allergen research: proteomics of shellfish allergen
It’s important to know what you’re eating, especially if you suffer from a food allergy.
About 220 million people worldwide live with a food allergy.1 These numbers, along with the complexity and severity of conditions, continue to rise. In America, there are about 32 million food allergy sufferers—5.6 million of those are children under the age of 18.2.2 That’s 1 out of every 13 children, or about 2 in every classroom. From a financial perspective, the cost of food allergy childcare for US families is up to $25 billion
