HemaCare Adds GMPrimeTM Cryopreserved Leukopak to its GMP Product Portfolio

, a Charles River Laboratories International, Inc. (NYSE:CRL) company and global leader and trusted brand in the customization of human-derived biological products and services for biomedical research, drug discovery, and cellular therapy process development, today announced that it has expanded its portfolio of GMP-compliant cellular material with the launch of the GMPrime cryopreserved leukopak. The GMP-compliant cryopreserved leukopak includes a quality assurance (QA)-reviewed Certificate of Analysis, thus adding QA review to HemaCare’s popular research use (HemaPrimeTM) cryopreserved leukopak. HemaCare’s GMPrime leukopaks are cryopreserved following a proprietary cryopreservation process and meet the requirements of the most rigorous quality standards required by regulatory agencies. GMPrime cryopreserved leukopaks extend shelf life and stability and provide researchers and cell therapy developers with the consistency needed in a cellular starting material used for the development and commercialization of next-generation cell and gene therapies.

Maintaining optimal function of key raw materials used to develop cell-based therapies is of prime importance. Factors such as site-to-site or international shipping of fresh leukopaks will impact cell viability and function. Cryopreserving a leukopak directly following collection significantly improves complex logistical hurdles by protecting product quality, mitigating risks during shipping, and allowing scheduling flexibility when planning and coordinating downstream processing activities, ultimately giving researchers and clinicians the freedom to plan, prepare, and perform studies on their timelines while preserving viability and functionality.

“Cryopreservation of leukopaks plays a critical role in the research and development continuum as this process simplifies complex logistics typically involved in working with raw human starting materials such as shipping, planning, and resource allocation while also providing the consistency, stability, and quality the industry desires,” said Dominic Clarke, Ph.D., Global Head of Cell Therapy for HemaCare. “The launch of HemaCare’s GMPrime cryopreserved leukopak ensures the industry experiences a flexible and seamless transition as they move their therapy from research to commercialization.”

GMPrime cryopreserved leukopaks are collected within HemaCare’s FDA-registered collection center from IRB-consented donors and immediately cryopreserved onsite within Class A and B (ISO 5 and 6) cleanroom environments. HemaCare’s HemaPrime and GMPrime cryopreserved leukopaks adhere to the same stringent quality standards and are collected and processed following standardized protocols to ensure the highest achievable purity, viability, and quality thus ensuring researchers can seamlessly transition from development to clinical trials to commercialization with confidence.

Vermilion Compass: Weekly Equity Strategy

Back to Near-Term Bullish on SPX and QQQ We downgraded our near-term outlook on the S&P 500 (SPX) and Nasdaq 100 (QQQ) to neutral last week (11/19/25 Compass), after being bullish since our 4/22/25 Compass, while maintaining our intermediate-term bullish outlook (as of our 5/14/25 Compass). Crucial support levels of 6480-6520 on SPX and $580-$583 on QQQ held last week, and we are right back to being near-term bullish as long as these support levels continue to hold. Just know that SPX could see...

Vermilion Compass: Weekly Equity Strategy

6550-6569 S&P 500 Support Holding For Now After 5.5-months, the S&P 500 (SPX) has now failed to break and stay below the its 20-day MA. However, 6569 has been our level that needs to break in order for us to have confidence that a pullback has begun; SPX made a low of 6551 on Friday (less than 20 points or 0.3% from our 6569 level), meaning it was not a decisive breakdown (in time or price). As a result, our near-term bullish outlook since our 4/22/25 Compass remains intact, and it will stay t...
