Molecular Biology

MarinBio’s expert team blends microbiology, genetics, biochemistry, biophysical chemistry and cell biology expertise with molecular biology and product development experience to achieve rapid results in a wide range of applications. Whether it is identifying a specific gene, manipulating or cloning a gene or producing and characterizing a protein drug product from a cloned gene or identifying/characterizing a drug metabolite, MarinBio makes it happen successfully for contracting clients. Our services include:

  • Unmatched quality
  • Prompt timelines
  • Cost-effective solutions
  • Exceptional communication

MarinBio assists you throughout the drug development process, including IND/BLA applications, commercialization, and pharmacokinetics (PK). We engage directly with the FDA and work closely with our clients to achieve their goals.


Molecular Biology looks at the molecular mechanisms behind processes such as cell replication and function. Simplified, it studies how genes are transcribed into RNA, how RNA is translated into protein, and control pathways. Commonly used techniques include gene cloning to identify and replicate individual genes and Polymerase Chain Reaction PCR to measure specific genes or message RNA. 

Microbiology is the study of microorganisms, unicellular (single-celled) and multicellular. In microbiology, the areas of antibiotics and vaccination are of particular interest. The use of bacteria as tools for analysis of biological mechanisms and of production of drugs is also important.

MarinBio’s professional scientists are expert at areas as follows:

  • Drug or Agent Minimum Inhibitory Concentration (MIC)
  • Phage display to identify high affinity and selective protein sequences
  • Plasmids and recombinant viral vectors
  • Gene expression, QRT-PCRQPCR, Real Time-PCR, Southern & Northern blots
  • Reporter assays
  • siRNAgene silencing and other gene regulation (see gene expression below)
  • Transfection & lipofection – electroporation / viral-based, lipid-based, cationic, transient, stable cell lines; see also transfection and exosome pages
  • Vector construction

Biochemistry & Biophysical Chemistry: Recombinant Protein Production, Purification, Characterization & Stability

When MarinBio clients require designer protein product production, purification and characterization

from transfection producing transient or stable cell lines, our staff PhD scientists have many years

of experience and successfully perform these client projects. Our niche is to take cross scientific

 field projects in molecular biology and biochemistry, biophysical chemistry, genetics, microbiology

and cell biology in bringing our breadth of expertise to successfully complete client projects, for

example, as follows:

  • Recombinant protein productionin cultured cells –bacterial/plasmid vectored cells, –insect

          cells/Baculovirus vectored, –yeast cells, –mammalian cells

  • Inducible cell or viral vectored gene promotors and specific cell signalingfactors for high

          level protein expression

  • Protein size, charge, conjugation, stability; Western blots for proteins and Eastern blots

          for post-translational modifications

Characterization: Protein size, charge, pI (Isoelectric point, pH where net charge on

protein is zero), stability, Eastern blots for post-translational modifications

  • Western blots, ELISAs, proteomics, drug binding protein assays
  • Enzyme assays, protein assays, reactive oxygen species assays
  • Ligand binding, affinity, inhibition, metabolic and radioisotope assays
  • Native protein purifications from plasma, cells, tissue extracts
