GMP & GLP TESTING

We are a GLP and GMP certified EU-located company providing testing specialized in molecular genetic based methods (NAT – nucleic acid tests). Our typical partners are general CROs outsourcing their DNA/RNA-based tests elsewhere. For (pre)clinical trials, we offer tailored analytical methods according to CROs´ demands. We also provide QC for batch release for pharma products as well (GMP testing).

Regarding biological drugs such as gene therapy compounds, biomolecules, vaccines, etc., GENERI BIOTECH covers all stages of development of a new drug – beginning with drug discovery via GLP preclinical testing phase up to later clinical tests.

When the development is successfully concluded, we provide DNA/RNA-based testing for the manufactured pharmaceutical cGMP.

Nucleic acid DNA/RNA – Biodistribution studies

Cell and gene therapy are new branches of pharmaceutical research, which use new types of drugs and strategies. New types of analytical methods are obviously needed. These methods are mostly based on DNA or RNA analysis, which is not surprising, as nucleic acid such as viral vectors, naked DNA (like plasmid, oligonucleotide) or RNA, as active agens is typically used for methods of gene therapy.

Authentication of cell lines

Authentication of human cell lines is based on DNA finger print analysis, which compares so-called "short tandem repeats" (STR), segments of genomic DNA of the tested cell line, with identical segments of a cell line with a confirmed identity. STR profiles for many of cell lines are published in reviewed databases.

Residual DNA tests

Much like typical chemical compounds, nucleic acid gene therapy agens, such as plasmids/vectors, viral particles and other, need quality control as well. Mostly it is a detection of unwanted contaminants what is needed. These contaminants originate from production systems where DNA was prepared, either from a cultivation media or as natural contaminants or from the changed original molecule.

Plasmid tests

Plasmid DNA is currently gaining increasing importance for clinical research applications in gene therapy and genetic vaccination. For direct gene transfer into humans, good manufacturing practice (GMP)-grade plasmid DNA is mandatory.

Nucleic acid (NA) sequence control

Correct sequence control - check if the sequence is free of mutant variant (insertion, deletion, changes), checking the sequence of interest is a good idea. Sanger sequencing method is a gold standard.

DNA genotyping

Genotyping is the process of determining differences in the genetic make-up (genotype) of an individual by examining the individual's DNA sequence and comparing it to another individual's sequence or a reference sequence.

Gene quantification (qPCR)

Mycoplasma detection

Mycoplasma contaminants may be introduced into cell culture and other biological products through master seeds, master cell seed (stock), starting materials of animal origin, and in processing of biological materials during passage and product assembly.

Endotoxin detection

This test reveals contamination by bacterial endotoxins (lipolysaccharide), which is a membrane component of gram-negative bacteria. This reaction is the basis of LAL test, used for detection and quantification of bacterial endotoxins.

Adenovirus detection

Adenoviral vectors serve as oncolytic viruses in many applications and our laboratory has experiences with detection method development, validation and sample analysis. Good example for adenoviral vectors is CGTG-102 (or ONCOS-102), which is in clinical phase now.

DNA/RNA integrity

Integrity of DNA/RNA is very important test needed according to the Europe pharmacopeia chapter 5.14. Mostly the test can be done as agarose gel electrophoresis or using advanced techniques such as PCR or fragment analysis.

Organism identification

If organism identification is needed the analysis of DNA fingerprints is method of choice. For identification so called DNA barcoding method can be used. This method uses a DNA analysis of specific sequences to identify an unknown sample in terms and classify it to particular species.
