A variety of post-translational modifications (PTMs) can impact a biotherapeutic protein’s mass, but none are as common as glycosylation.[1] Hence, the headline for a recent article in Genetic Engineering and Biotechnology News, “Post-Translational Icing on the Biologics Cake,” featuring comments from Sean McCarthy, Ph.D., Global Market Manager of Biologics at SCIEX.

New features in OneOmics suite
I just wanted to thank the readers here, both the OneOmics suite users who’ve shared their time and watched OneOmics grow, and for all the talented developers and scientists who’ve made OneOmics suite what it is today.
Assess the performance of the Echo® MS system
To obtain the best, most reproducible results using the Echo MS system, it is important to select the best solvent for your analyte and matrix and to ensure the flow rate is optimized for your solvent. Please review this flow rate optimization community post to...
Merging two FASTA files
There is an easy way to merge two FASTA files together. Open notepad and type this string: type %*>"newfile.fasta" Enter any name for the FASTA file between the quotes. Save the file as: Merge FASTA files.bat Copy the two files you want to merge into the same...
Intabio acquisition expands SCIEX portfolio of impactful solutions to accelerate biotherapeutic development
Due to the nature of their production, biotherapeutics are difficult to manufacture. Growth conditions, purification protocols and formulation requirements can introduce unintended modifications into the protein structure that may affect its efficacy and safety.
Breaking down the SCIEX Triple Quad™ 7500 LC-MS/MS System – QTRAP® Ready
Sensitivity and robustness carry different meanings in the world of mass spectrometry. Generally, sensitivity refers to an instrument’s ability to achieve lower limits of detection (LOD). Robustness, on the other hand, refers to an instrument’s ability to consistently...
Importing acquisition methods from Analyst software to SCIEX OS software
The SCIEX Triple Quad 7500 system is the first nominal mass instrument to be released completely on SCIEX OS software. Moving to a new software solution can be time consuming with the need to transfer numerous methods to the new platform. SCIEX OS software helps...
The honey sting
As a consumer it’s hard for me not to feel inundated with claims that our food is “all-natural” or “chemical-free” or that we should buy certain “superfoods” for their health benefits. We read labels and trust that the product we are buying is what we are truly...
Innovation that’s blasting through limitations in explosive detection
Mass spectrometry’s important role in identifying explosives The need for rapid explosive detection is now an unfortunate reality. The remit is multifaceted. The first is for preventative purposes, to protect us from any threat to life. The second is in the...
A new generation of therapeutic modalities
There are over 7,000 genetic diseases that could potentially be cured using gene therapy. Rare metabolic diseases, autoimmune disorders, cardiovascular disease and cancers are some of the top disease classes that can be addressed with gene therapies. With over 1,000...
Enhancing Biologics with CESI-MS Characterization
Comprehensive characterization of a biologic requires analysis at both the intact and digest levels, but these analyses can be complex and cumbersome. For example, with conventional liquid chromatography separations, researchers are often left with limited information...
