Improve Your Vaccine Development Process with Simple Western

Widely used to improve reproducibility, quantitation, throughput and time to market, Simple Western can help you develop and characterize your vaccine candidates. With the ability to separate proteins by Size or Charge, Simple Western offers unparalleled speed and insight leveraged throughout the vaccine development process. Simple Western can be used to measure protein in crude cell lysates in upstream samples as well as in samples further downstream to detect impurities and assess vaccine quality and vaccine efficacy.

More Advantages in the Vaccine Development Process

By offering automation, reproducibility, sensitivity, and quick time to results, Simple Western has proven to be an invaluable tool throughout all stages of vaccine development

  • Quantitation. Truly quantitative immunoassays using conventional Western blot antibodies and built-in total protein normalization.
  • Reproducibility. Eliminate the variation of traditional Western blots, with intra-assay CV’s of <15%.
  • Sensitivity. Stellar™ NIR/IR Modules for Jess™ with industry-leading sensitivity for fluorescence Western-blotting workflows.
  • Throughput. Process up to 96 samples per automated overnight run. Screen vaccine candidates with triplicate data points. Get even more data points per sample with RePlex™ and lower the cost per data point. 
  • Method transferability. Using Compass for Simple Western, all data and records are digital, allowing for easy analysis, transfer and archiving between sites or from sponsors to CROs.
  • Compliance. 21 CFR Part 11 compliant, ready for your organization’s regulatory needs.

Get the Complete Picture of the Humoral Response

Rich Multi-Analyte Characterization

Simple Western assays can help measure serum antibody levels to confirm immune responses against an antigen and to test for antibody production in response to vaccination. In this application note, we used Simple Western to detect autoantibodies in lupus patient serum as a model system to generate proof-of-concept data for the assay.

Multi SARS-CoV-2 Antigen Serological Assay data set

Compared to a single antigen assay, Simple Western serology assays can be used to detect serum antibodies against multiple different antigens simultaneously to give a more complete view into the humoral response. The SARS-CoV-2 Multi-Antigen Serology Module for Simple Western can be utilized to detect and quantify the humoral response to five key SARS-CoV-2 antigens in serum or plasma simultaneously in a single capillary while also providing molecular weight information of each antigen, all without compromising sensitivity.

Maximize Vaccine Efficacy

Congenital infection of human cytomegalovirus (HCMV) is one of the leading causes of non-genetic birth defects, and development of a prophylactic vaccine against HCMV is a top priority for public health. Learn how researchers are using Simple Western for measuring vaccine efficacy by monitoring a pentameric complex that is critical for HCMV vaccine development.

High Sensitivity for Vaccine Quality Control

Simple Western assays are great at detecting process-related contaminants for vaccine quality control, like HCP, Protein A, GFP, and BSA. In this application note, learn more about how Simple Western platforms detect contaminants with the sensitivity needed to confirm if their concentration falls below regulatory guidelines.

Total Protein Detection that Beats SYPRO Ruby

Purity of the final vaccine product is often confirmed using detection methods like SYPRO Ruby or Coomassie staining methods which reportedly require lower nanogram levels for reliable detection. The precision, sensitivity and flexibility of Simple Western surpasses traditional approaches for detecting process-related contaminants. The 5X total protein labeling reagent in conjunction with RePlex to achieve ultrasensitive total protein detection enables researchers to detect low abundance impurities, get the most data out of their precious samples, and normalize their protein expression data with confidence.

Easy Monitoring of Vaccine Stability

Scientists at Merck & Co., Inc., rely on Simple Western to monitor the stability of polysaccharide-protein conjugate vaccines with the added advantage of being able to detect degradation products at very low concentration and under full automation, can reduce potential analysis error and analyst benchwork while having the benefits of speed and higher throughput with 96 capillaries.

Increase analytical capacity. A higher volume of information in a relatively short time.

Increase product coverage for a wide spectrum of vaccine product development. Discovery, preclinical, clinical, and commercialization in both the biopharmaceutical and vaccine industries.
