Common Reagents

Irvine Scientific’s cell culture reagents are made with the highest quality and consistency, allowing our customers to enjoy reproducible results.

Biological buffers are used to supplement cells in culture.


HEPES is a zwitterionic organic chemical buffering agent and one of the 12 Good's buffers. HEPES is widely used in cell culture.


PBS provides a buffer system to maintain cell culture media in the physiological pH range or to irrigate, transport, or dilute fluid while maintaining cell tonicity and viability.


Salt solutions are used in cell culture to maintain the pH and osmotic balance, as well as provide cells with water and essential inorganic ions.


Hanks’ Balanced Salt Solutions (HBSS) is used in cell culture to maintain the pH and osmotic balance, as well as provide cells with water and essential inorganic ions.


Irvine Scientific recognizes that a reliable source of highly Purified Water (PW) is fundamental to the success of any operation. Produced from an advanced, state-of-the-art Water for Injection (WFI) system, Irvine Scientific’s WFI Quality Water is the most suitable water available for producing cell culture media, the reconstitution of biochemical reagents, and as final rinse water for critical applications. WFI Quality Water meets and exceeds both USP and EP specifications.


The ability to preserve and thaw primary and stem cells has tremendous potential in allogeneic and autologous transplants for clinical therapeutic applications. Irvine Scientific’s biopreservation products are formulated as chemically-defined, protein-free solutions that are manufactured under GMP.


PRIME-XV® FreezIS enables cell freezing of a variety of cell types, ranging from human mesenchymal stem cells and induced pluripotent stem cells to rat neural progenitor cells. After cryogenic preservation, cells were validated for cell markers, viability, and fold expansion over multiple passages. PRIME-XV FreezIS follows a slow freezing process to reduce damage from cold shock.


PRIME-XV® Hypothermic Preservation Solution provides a novel method of storing and shipping biologics at 2°C to 8°C, and reduces the cellular stress response from the chilling and re-warming of cells and tissues. PRIME-XV Hypothermic Preservation Solution is a safer and easier method of biopreservation that is ideal for short term storage or cells that are sensitive to freezing temperatures.
