Bioanalytics and Protein Characterization Expertise

Supporting today’s ideas and tomorrow’s biotherapeutic solutions

As developers explore an increasingly diverse array of biotherapeutic molecule types and configurations, a partner with the capacity for efficient turnaround, state-of-the-art instrumentation and techniques, and a highly-skilled bioanalytics and protein characterization team is needed. Our bioanalytics team is here to meet these demands.

While clients trust us to deliver dependable and reliable bioanalytical services, we’ve never accepted the status quo. Whether exploring alternative approaches to protein production via our FastPharming® plant-based protein expression system, using our Glycaneering Service℠ to tailor and control N-glycosylation for next-generation antibody engineering, or leveraging mass spec multi-attribute methodology to improve efficiency, we have a unique perspective on the world of biotherapeutics.

To support great biotherapeutic ideas, no matter the routes utilized and who is developing them, our bioanalytical services team is here to help advance biotherapeutic research and development.

Reverse phase HR/LCMS on a Sciex X500B TOF/5600 TOF mass spectrometer

Data Samples
Data Samples
Line graph with Intensity on y-axis from 1-100 in increments of 20 and Mass (kDa) on x-axis from 144-148. Lines peak at high intensities signifying detection of a protein. Different peaks indicate different glycoforms attached to the protein.
Line graph with Intensity (cps) on y-axis from 0.0e0-3.5e5 in increments of 1.0e4 cps and Time (min) on the x-axis from 0-33 in increments of 1 min. The sample is deglycosylated, so the high intensity peak indicates the protein homogeneity without glycoforms attached.

Reverse phase HR/LCMS on a Sciex X500B TOF/5600 TOF mass spectrometer

Data Samples
Data Samples
Line graph with Intensity (cps) on the y-axis from 0-8000 in increments of 500 cps and Time (min) on the x-axis from 0-33 in increments of 1 min. Sample is digested into light chain (LC) and heavy chain (HC) fragments. The high intensity peaks indicate LC and HC forms.
Line graph. Absorbance at 220 nm (AU) on y-axis from 0.000-0.015, increments of 0.001. Time (min) on x-axis. High absorbency peaks indicate LC and HC and can distinguish HC non-glycosylated from HC glycosylated. Then compares these to the internal standard.
Line graph. Intensity (cps) on y-axis from 0.0e0-7.5e5 in increments of 5e4. Time (min) on x-axis from 0-33 in increments of 1 min. Sample is digested into Fc and Fab antibody fragments, therefore high intensity peaks indicate Fc and Fab fragments.

Data Samples
Line graph with Intensity (cps) on the y-axis from 0-10000 in increments of 5000 cps and time (min) on the x-axis from 0-21 in increments of 1 min. The protein is deglycosylated and high intensity peaks indicate the glycoform(s) that was/were released from the protein.
Line graph with RFU on the y-axis from 0-40 in increments of 2.5 and Time (min) on the x-axis from 0-6 in increments of 0.2 min. The protein is deglycosylated and high intensity peaks indicate the glycoforms(s) that was/were released from the protein.
