1978 was a great year for scientific advancement – NASA hired the first women astronauts, the first test tube baby was born and List Labs was founded. Linda Shoer, our founder, saw an opportunity when she realized there was a need for a commercial supplier of Cholera Toxin for studies in signal transduction and neuronal track tracing. On May 18, 1978, Linda started something more than a company, she started a family- the List Labs family.

List Labs’ catalog has grown to include over 100 products, which have been used in thousands of scientific research projects over the years. More recently we have added services to our offerings; this trend started in the early 90’s when List Labs manufactured Botulinum Toxin (Botox) for Allergan. Since then our services have expanded to include cGMP grade manufacturing, live biotherapeutics products, scalable process development for fermentation, purification and lyophilization, enhanced QC testing and more! We’ve also added to our team of experts with employees in Microbiology, Production, QC, QA, Sales and Marketing, Shipping, Administration and Finance.

List Labs carries on the values instilled by Linda Shoer and continues to grow our team, our capabilities and experience. We are excited to see what the next 40 years bring!

The terms “Microbiome” and “live biotherapeutics” have been repeated frequently in the last few years in scientific circles. Researchers are understanding more and more about the various microbiomes in the human body and how they affect our overall health. From this research, microorganisms have been identified that may be beneficial to our health and could be used as a therapeutic, otherwise known as a live biotherapeutic products. This article explains an overview of some microbiome and live biotherapeutics basics.

What is Microbiome? 

The human microbiome is the collection of trillions of microbes living in and on the human body. Scientists believe that it plays a role in many basic life processes and are important to our health.  Perturbation of the microbiome has been associated with a growing number of diseases including inflammatory bowel disease, allergies, asthma, autism, and cancer.

What are some different types of human microbiomes? 

Microbiomes are found, for example, in our gut, skin, vagina, and mouth.  Each of these sites have a different consortia of microorganisms.  Beneficial microorganisms have been identified in each of these niches.  Researchers are studying the various human microbiomes to better understand their importance in health and disease.

What is a Live Biotherapeutic Product (LBP)? 

A live biotherapeutic product contains a live microorganism that is used for the prevention, treatment, or cure of a disease or condition. As the characterization of the human microbiome and its link to human health has become better understood, microorganisms have been identified which may have a health benefit.  The use of these microorganisms as a live biotherapeutic product in clinical application shows great promise.  Several clinical trials are underway to evaluate their potential as a therapeutic.

What equipment and facilities are necessary for the production of a Live Biotherapeutic Products?

Many of the microorganisms identified for the manufacture of live biotherapeutic products are obligate or strict anaerobes and spore forming organisms.  These type of organisms present unique challenges to the emerging microbiome therapeutic space.  In particular, many of the microorganisms are anaerobes which cannot be exposed to air and thus expertise is required in handling and cultivating the organism.  Facilities and equipment important for the cGMP manufacturing of these organisms include:

• Biological safety cabinets
• Anaerobic work stations with internal HEPA filtration for aseptic, anaerobic fill capability
• Equipment to scale the process cultivation
• Stainless steel or single use bioreactors
• Closed harvest systems such as tangential flow filtration with hollow fiber membranes
• Semi-automated or automated filling equipment
• Freeze drying equipment, i.e. Lyophilizer
• Homogenization and milling equipment

While most of List Labs’ products are intended as research reagents (Research Grade), several can be produced as GMP products for use in humans. Below are key differences between the two.

Research Only VS Preclinical/Clinical/Human Use

Reagent grade products for research only are labeled “not for human use” but are produced using good laboratory practices. These reagents are readily available on our website and any quantity can be purchased. Products intended for human use are produced under cGMP (current Good Manufacturing Practices, see the Code of Federal Regulations 21 CFR 211) and are provided to clients with a customized contract.

cGMP = Higher Production Standards

Producing compounds under cGMP regulations is a more costly process compared to reagent grade. cGMP compliance includes all aspects of production: documented training programs, QA issued production records, dedicated production suite preparation, testing and release of raw materials, analytical method qualification dedicated supplies, and validated cleaning methods. In addition, a Drug Master File may be submitted to the FDA, which can be cross referenced by our GMP customers.

See more about our cGMP production capabilities.

One example of a product produced as both reagent grade and GMP grade is HPT™ E. coli O113 LPS. Although a chemist may not be able to tell the difference between the reagent grade and the cGMP material, the difference is in the compliance to the GMP’s as described above. Our reagent grade material is produced with good laboratory procedures, however it is not compliant to GMP. Consequently, reagent grade E. coli LPS is not for human use and cGMP LPS may be applied “for human use” per FDA approval. cGMP for human use is not so much a property of the E.coli LPS as it is describing the environment and procedures surrounding the preparation of the compound.

For example….

Our LPS from E. coli O55:B5 or E.coli O113, Products #203, #423 and #433, are reagent grade products and are often used in research, particularly for inducing the maturation of Dendritic Cells.

We also provide cGMP LPS from E.coli O113 on a contract basis, which is made compliant to GMP and is appropriate for FDA approved use in humans.
