KJ Scientific LLC is a certified Woman Owned Small Business (WOSB) and Historically Underutilized Business (HUB) with a global reach. We have locations in Texas and Switzerland.
KJ Scientific was founded with a mission of ensuring human and environmental health through rigorous testing and analysis of the chemicals and products introduced to the market. To uphold these high standards, we became the first product testing lab in the world to exclusively use new, innovative in vitro technology in our chemical testing products and services.
This alternative animal testing method reduces research and testing costs by up to 50%, decreases experimentation time by up to 50% and significantly cuts down on the number of animals required for testing by nearly 100% – all while delivering highly reliable and sustainable chemical analysis.
KJ Scientific has extensive experience testing and analyzing a wide range of chemicals and products such as agrochemicals, pharmaceuticals, cosmetics, personal care products, fragrances, consumer goods and many more.
Our product testing lab offers full, customized studies of chemicals for identification of metabolic rates and bioaccumulation potential.
We provide world class products to those who conduct their own bioassays, sourced from reliable rainbow trout strains. Our scientists believe in our liver S9 subcellular fraction and cryopreserved hepatocytes so much that we use them exclusively in our own testing.
KJ Scientific has proven world-leading expertise and experience in this field. We are one of seven laboratories that participated in the OECD Ring Trial which resulted in the development of test guidelines TG 319A and 319B on determination of in vitro intrinsic clearance using rainbow trout cryopreserved hepatocytes and liver S9 subcellular fractions. We partnered with Fortune 100 Companies on the multi-year process to establish the guidelines that all laboratories conducting in vitro experiments must follow.
The scientists of our product testing lab have extensive knowledge of Good Lab Practices (GLP) protocols and conduct all experiments and processes in the Spirit of GLP. Our high testing standards ensure strict protection of environmental health and reduce harm to animals throughout the testing process.
We understand that our work can identify the potential risks of substances on the health of humans and wildlife, and so we guarantee that our products and services are delivered with the highest levels of integrity, responsibility, accuracy and dependability.
KJ Scientific offers tailor-made products and services for your specialized needs. Connect with us and discover how our company can help your company!Request More Information
A native of Costa Rica, Dr. Johanning has dedicated her professional life to study different aspects of environmental biology and ecotoxicology in relation to human and environmental health.
Dr. Johanning’s interest is in vitro metabolism and its application to determine fish bioaccumulation potential of chemicals. She has worked in both academic and industrial settings. In 2012 she decided to start her own consulting firm KJohanning Consultancy advising the chemical industry in the use of a new technology, the trout in vitro metabolism assay, an alternative method to assess bioaccumulation potential. Dr. Johanning is also an active member of the ILSI/HESI (Human and Environmental Sciences Institute, Washington, D.C.) Bioaccumulation Subcommittee. After consulting for several years, she decided to open her own biotechnology company, KJ Scientific, in 2014 in Georgetown, Texas. This new product testing lab – in collaboration with SC Johnson – participated in the OECD Ring Trial with seven other laboratories (DOW, Du Pont, EPA, Fraunhofer, Givaudan, Proctor & Gamble, SC Johnson). The Ring Trial resulted in the validation of OECD Test Guidelines 319A and 319B. Dr. Johanning was also a member of the Expert Group for the OECD Ring Trial along with other scientists from both Europe and the United States.
Dr. Johanning coordinates and teaches at the professional training courses at SETAC (Society of Environmental Toxicology and Chemistry) on the use of trout in vitro metabolism assay. She worked for several years at Life Technologies/Invitrogen (now Thermo Fisher Scientific) and CellzDirect as a Study Director responsible for overseeing drug metabolism studies, and leading an emergent ecotoxicology unit. Dr. Johanning coordinated the activities for production of trout liver fractions (S9 and microsomes) and cryopreserved hepatocytes. Previous to this position, she worked as a Sr. Research Scientist in the Environmental Endocrinology Lab at the Center for Bioenvironmental Research at Tulane University (New Orleans, LA) in the field of endocrine disruption. She received her M.Sc. from the Dept. of Aquaculture and Fisheries and her Ph.D. from the Dept. of Zoology from the University of Rhode Island where as part of her research she studied biochemical/physiological parameters in her research using Atlantic salmon and tilapia.
Dr. Johanning has also conducted medical research. She did post-doctoral medical research in the Dept. of Biochemistry at the Louisiana State University Medical Center and at the Tulane University Cancer Center in the Medical School. She earned her B.S. degree (Zoology and Marine Biology) from the University of Costa Rica in her native country of Costa Rica. Karla has been an Adjunct Visiting Professor at Nicholls State University in Louisiana.
Dr. Johanning’s goal is to build a biotech company where companies can test their chemicals utilizing an array of biochemical assays to comply with the regulations that are being placed by national and global regulatory agencies.
