Whole Tissue Cryoprotective Media (WTCM-D) with DMSO

(18 customer reviews)

Cryopreservation of tissues especially when a big portion is intended to be used is challenging. Additionally, the biggest obstacle is forming ice crystals inside the cells.  This inevitably, cause volume expansion with the destruction of cell membranes and holes in loose connective tissue. Whole Tissue Cryoprotective Media (WTCM-D) with DMSO, preserve tissues during rapid freezing. This remarkably promotes  formation of amorphous ice ( rather than crystal ice).

Description

Background

Cryopreservation of tissues especially when a big portion is intended to be used is challenging. Additionally, the biggest obstacle is forming ice crystals inside the cells.  This inevitably, cause volume expansion with the destruction of cell membranes and holes in loose connective tissue. Whole Tissue Cryoprotective Media (WTCM-D) with DMSO, preserve tissues during rapid freezing. This remarkably promotes  formation of amorphous ice ( rather than crystal ice).

PurMa™ WTCM-D  has particularly overcome several challenges

  1. Liquid nitrogen has a low specific heat constant.  When it contacts warm tissues or OCT it boils and forms a vapor barrier and acts as an insulator. As a result, the inner core of the tissue sample freezes slowly and unevenly. This is especially more challenging when the tissue sample is large. The cryoprotective agents in PurMa™ WTCM-D precents this to happen by penetrating rapidly inside the tissue.
  2. PurMa™ WTCM-D acts regardless of the size of the tissue. PurMa™ WTCM has high thermal conductivity. This, therefore, can allow liquid nitrogen for rapid and efficient cryoprotection.
  3. PurMaTM WTCM contains ingredients which makes it suitable for the preservation of rigid tissues.

Special Features

  • Ready-to-Use.
  • PurMaTM WTCM provides much higher cell viability after short/long-term cryoprotection,
  • PurMaTM WTCM Prevents the formation of crystals in extracellular space. This, consequently, prevents cellular dehydration and resulting in less exposure to toxins from the non-recovering cells.
  • Preserves morphological appearance as a standard factor of cell recovery.
  • Tested for pH, osmolality, sterility, and endotoxin.
  • Each Lot of PurMaTM WTCM is tested for pathogens and sterility. We evaluate each Lot as well for several criteria. Including survival (by Trypan Blue method), viability & performance (by MTT Test), and the recovery rate by Alamar Blue test.
  • PurMaTM WTCM has been tested successfully for several commonly used tissue including rodent heart, brain, and kidney.

    Review: I have worked directly with PurMa biologics on a number of projects ongoing in my lab. I find the media and the specialty Lipid Depleted Serum to be high quality and very consistent among batches, which is critical to our adipogenesis projects using primary stem cells. Also, the service from PurMa is outstanding for my lab.

    Review: I started my lab using the regular Gibco media components. We have shifted to Purma past 6 months and see no difference in the quality of our cell culture. Simply saying that Purma is cheaper, quicker to deliver and as good as Gibco. The best part was that Purma customized several media for our fish cell lines which was really helpful. Lastly, Seif walked through the customization of media over Zoom, that gave a lot of confidence for using those media solutions.

    Review: Reliable and dependable products. We purchased lipid-depleted FBS (LD-FBS) from PurMa Biologics and it worked great. We cross-checked the lipid content in the serum by GC-MS and Triglyceride assay and as advertised, did not find any lipids in the FBS.
