Sepax Literature Review: Our Unix-C SEC-300 columns were used to detect the different engineered regions in the RV1/3 in paramyxovirus in this Janssen study: Universal Paramyxovirus Vaccine Design by Stabilizing Regions Involved in Structural Transformation of the Fusion Protein . The study results conclude that our columns demonstrate that the SEC-MALS method can accurately detect protein sequence modification for prefusion f which is critical for future vaccine development.

The oxidation of the complementarity-determining region (CDR) in monoclonal antibodies (mAbs) is a critical quality attribute that can affect the clinical efficacy and safety of recombinant mAb therapeutics. In this new study from Henlius Biologics, a robust hydrophobic interaction chromatography (HIC) method was developed to quantify and characterize CDR oxidation variants in mAb-A by using a Proteomix Butyl-NP5 analytical and preparative column.

📢 The US Pharmacopeia (USP) has released the 3rd draft edition of the guideline "𝐀𝐧𝐚𝐥𝐲𝐭𝐢𝐜𝐚𝐥 𝐏𝐫𝐨𝐜𝐞𝐝𝐮𝐫𝐞𝐬 𝐟𝐨𝐫 𝐐𝐮𝐚𝐥𝐢𝐭𝐲 𝐨𝐟 𝐦𝐑𝐍𝐀 𝐕𝐚𝐜𝐜𝐢𝐧𝐞𝐬 𝐚𝐧𝐝 𝐓𝐡𝐞𝐫𝐚𝐩𝐞𝐮𝐭𝐢𝐜𝐬". Three columns from Sepax were being selected again in this new release: ✔ SRT SEC-1000 - mRNA Aggregation (PN: 215950-7830) ✔ Protemix RP-1000 - mRNA Percent of Fragments (PN: 465950-2110) ✔ Zenix SEC-300 - mRNA Aggregation Quantitation (PN: 213300-4615) https://lnkd.in/ehExJvRX #USP #mRNA #Vaccines #QualityStandards #HPLC #Analytical

Introducing a rapid, straightforward, and precise quantitative method for the analytical separation and quantification of empty and full AAV8 capsids using AEX-HPLC MALS. Sepax has developed a new SAX surface chemistry specifically designed for the full separation of empty and full AAV capsids. An AAV8 standard with UV-MALS detection is used in the resin batch quality control process and batch release to ensure minimal noise interference and excellent lot-to-lot consistency for high accuracy in molecular weight calculations and precise analysis.

Another great summary from Anthony Sokol on how our Sepax wide pore #analyticalcolumns were used to assess the presence of aggregates vs. monomer species. Read his full summary to see how our SRT 1000 SEC HPLC columns unique surface coat, surface area, and pore distribution helped the researchers reach their goal. Read here: https://lnkd.in/e2amGsyA

The rain didn't stop our Sepax Family BBQ this past weekend! Yummy food, fun games, and good conversations were had by all.

This month's newsletter introduces new Proteomix® AAV SAX MALS columns, which are specifically designed for optimal separation of empty and full AAV capsids delivering a fast and easy quantitation method with excellent lot-to-lot consistency for analytical characterization and quality control.

Check out this paper review written by Anthony Sokol about our Zenix SEC columns. The researchers created a novel application using a rather unique mobile phase system for the separation. #MixedMode #SEC #Chromatography Link: https://lnkd.in/eUGwvH9x
