Activity in RNA-based therapeutics development has reached an all-time high & there is a large need for trusted, rapid analytical methods.


Avance Biosciences™ brings seasoned GLP- and GMP-compliant assay development, assay validation, and testing services to the exploding world of RNA therapeutics. The development and production landscape for mRNA vaccines and other RNA-based therapeutics is busier than ever. The success of the mRNA COVID-19 vaccines has served as an important validation of the safety and efficacy of this approach and demonstrated the flexibility and speed with which an RNA drug can address an unmet need. Drug developers are now using mRNA vaccines to address a broad array of new therapeutic areas, from Zika to cancer. Consequently, there is a considerable need for accurate, inventive RNA therapeutics analysis and expertise to keep up with the ever-evolving regulatory environment.

New Challenges for the RNA Therapeutics World

RNA-based drugs are distinct from small molecules and other biologics, presenting new analytical challenges and uncertain regulatory standards. In addition, the unveiling of multivalent mRNA vaccines adds the need for sophisticated assay development and molecular biology expertise. With the field growing and progressing so quickly, speedy mRNA characterization, pre-clinical/clinical testing, QC, and lot release are necessary to compete in the competitive marketplace.

Visionary Analytical Solutions, Expertly Executed

At Avance, we are experts at designing, developing, and validating molecular biology assays for RNA therapeutics development and manufacturing. That means faster and more reliable results and innovative solutions to your analytical challenges. We’ve worked at the leading edge of RNA-based therapeutics for a long time and have developed an extensive portfolio of GLP- and GMP-compliant assay services that surpass regulatory requirements.

Tests Descriptions
mRNA DS/DP Testing (CGMP)
ID Confirm the sequence of mRNA by sequencing cDNA by Sanger and NGS.
Size Determine mRNA size using CE, HPLC, Bioanalyzer, and/or northern blotting methods.
Ratio Testing Determine the ratio of mRNA in a mixture using RT-qPCR or ddPCR.
Residual Plasmid Testing qPCR-based assay to detect potential plasmid contamination.
Quantification Quantify mRNA using UV Spectroscopy, RT-qPCR, or ddPCR.
Protein ID IVT in cell-free medium and detection of the resulting protein using Western blot/ELISA.
Encapsulation Efficiency Determine mRNA/LNP encapsulation efficiency using RT-qPCR or ddPCR.
dsRNA Detection Detect various dsRNAs using immunoblotting, native and denaturing gel electrophoresis.
Potency Assay Develop and validate a custom IVT assay to determine mRNA potency.
Stability Assay Develop and validate a custom assay to evaluate the long-term stability of mRNA.
Mycoplasma Testing qPCR-based mycoplasma testing.
Endotoxin Testing Test potential endotoxin contamination using Limulus amebocyte lysate (LAL) method.
Custom Assays Develop or tech transfer custom assays from clients and validate/verify the assays for GMP testing.
Preclinical/Clinical Testing (GLP or non-GLP)
mRNA/LNP Biodistribution Study Develop and validate RT-qPCR and/or ddPCR assays and test tissues/blood from various animal models under GLP or non-GLP. Recovery will be evaluated with spiked mRNA, and the RNA standard curve will be used to correct RT efficiency. The standard curve method will be used.
mRNA Expression Analysis Develop and validate RT-qPCR and/or ddPCR assays and test human bodily fluids for mRNA expression. ΔΔCt method or standard curve method will be used depending on the nature of mRNA.
mRNA Human PK Study Develop and validate RT-qPCR and/or ddPCR assays and test human bodily fluids for mRNA expression. ΔΔCt method or standard curve method may be used.
E. coli Cell Bank and Plasmid Testing (GMP)
Lytic phage detection Detect potential lytic phage contamination in E. coli cell banks. A positive control is used to evaluate the assay’s validity.
Lysogenic phage detection Determine the presence/absence of lysogenic phage in E. coli cell banks with Mitomycin C induction. A positive control is used evaluate assay validity.
Strain Identification Various assays to confirm the identity of DH10β, K12, B, BL21, Stabl3 cell lines, as well as RecA and LacI genotyping.
Species ID API 20E test to confirm the species of the cell bank.
Gram Staining Differentiate Gram Positive from Gram Negative bacteria by staining with dyes.
Viability Testing A cell line sample is stained with trypan blue, and the percentage of viable cells is reported.
Purity Testing Aerobic and anaerobic culture to detect potential bacterial and fungal contamination. Various bacteria and fungi are used as controls.
Marker Retention Testing Percentage of cells that contain a selectable marker, such as an antibiotic-resistant gene.
Plasmid ID Double-stranded Sanger sequencing or NGS for full or partial plasmid sequence confirmation.
Plasmid Copy Number Using qPCR, quantify copies of plasmid per cell for characterization and genetic stability evaluation.
Restriction Digest Restriction mapping for plasmid identification and genetic stability evaluation.
