Established in 1994, Cell Marque primarily focuses on producing and marketing antibodies for diagnostic immunohistochemistry (IHC). Our main focus is providing quality and innovative antibodies for in vitro diagnostic use to further serve the clinical market. Cell Marque serves pathology laboratories and research facilities globally through a domestic sales force, our team of Technical Consultants, as well as international distributors. We are a company that encourages intellectual growth and it is our goal to stay on top of current issues in our industry so that we can bring our customers the newest and most innovative antibodies available.

In addition, Cell Marque manufactures and supplies primary antibodies to Ventana Medical Systems® (a member of The Roche Group) who is the world leader in automated IHC platforms. Lastly, we are one of the only IHC companies that employs a team of medical doctors, including two full-time pathologists, to deliver to our customers the level of quality and support they deserve.

Cell Marque operates out of a consolidated facility in Rocklin, California. The facility incorporates laboratories for hybridoma-derived antibody production, research and development, histology, and quality control as well as production floor space. Cell Marque is both ISO13485:2003 certified and 21 CFR Part 820 compliant and therefore offers our products to key markets worldwide. We have also taken an initiative to enhance our productivity through studied improvements in workflow (LEAN Enterprise) and the adoption of paperless document management software.

Cell Marque has grown every year without exception. We attribute this to diligent adherence to our Mission, Vision, and Values.

Vision Transforms into Reality

Established in Austin, Texas in September of 1994, Cell Marque opened its doors with a unique vision.

Deparaffinize, Rehydrate, and Unmask: Trilogy is Born

The early years of Cell Marque were filled with creative ideas and solutions to common problems seen in the IHC industry. Cell Marque invents and patents Trilogy™, a three-in-one pretreatment reagent, which has now become a staple in labs throughout the world. Trilogy™ is a revolutionary product that deparaffinizes, rehydrates, and unmasks all in one easy step. Trilogy™ allows labs to standardize their pretreatment process as well as reducing that process time by a productivity-boosting 45 minutes. This reduction in process time has made Trilogy™ a highly popular and sought after Cell Marque product. Cell Marque also patented its unique “bladder approach” to dispensing reagents from a dispenser without producing bubbles during the staining process. This innovative approach reduced the occurrence of false negatives in customer labs.
