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
Quantify and Identify Pesticides in Complex Food Samples Using the QTRAP 6500 LC-MS/MS System
Recent regulations on food analysis require screening for pesticides using confirmatory techniques, such as GC-MS and LC-MS/MS. More than 1000 pesticides are used worldwide and, along with their metabolites and degradation products, are present in food. There is a demand for powerful and rapid analytical methods that can identify pesticides with high confidence in a broad range of food matrices and quantify at low concentrations with good accuracy and reproducibility. Challenges for pesticide residue laboratories at the moment are the request to test for more compounds, in a wider range of samples, all without sacrificing data quality.

Bottom-Up Proteomics: A Discussion with Christie Hunter
Biocompare recently featured an article on Bottom-Up Proteomics. I had a chance to follow up with Christie Hunter and expand on some of the questions featured in the article:
Characterize and Monitor Host Cell Proteins (HCPs) Using SWATH Acquisition Technology
During drug development, the removal of impurities and purification of a final drug product is absolutely essential in order to ensure the safety and efficacy of a therapeutic drug. Of particular concern for biologics are impurities that can stem from host cell proteins. Because biologics are developed through cell culture and fermentation within a host cell, proteins from this host cell can be co-purified with the final biologic. These host cell proteins or HCPs can cause the final product to have undesired side-effects such as eliciting an immune response in patients taking the drug, or affecting the drug’s stability or efficacy. As a result, regulating agencies require drug companies to monitor levels of HCPs during the development and purification of a biologic and to remove HCPs to an acceptable level in the final biotherapeutic product.
Simplifying Biologics Bioanalysis Sample Prep
These days, everyone seems to be furiously scratching tickets to become instant winners, but I’ll bet you didn’t expect to find sample prep tips that way. For large molecule bioanalysis, preparing your samples can be one of the biggest challenges. It’s a whole different world from traditional small molecule bioanalysis. SCIEX has developed techniques and automation that make biologics sample prep simpler and faster, with reproducible results.
The Connection Between Mass Spectrometry and Space Exploration
Mass spectrometry has been used for some pretty fascinating applications in our world – like testing for steroid use in athletes1, measuring pesticides in grapes2, assessing the efficiency of a psoriasis drug3, and whether that expensive bottle of 100% olive oil is, well, really 100% olive oil.4 But did you know mass spec is also used out of this world? Like… in space?

LC-MS/MS Method for Biotherapeutic Drug Development Challenges
Traditionally, the pharmacokinetic profile of biotherapeutics such as insulin glargine, adalimumab, trastuzumab and others, used gold standard LBAs to assess dose-response during drug discovery and development. However, LBAs require a specific antibody reagent to be developed for each mAb variant, a process that is often incompatible with the compressed timeframes encountered during the initial stages of drug development.
