Plasma, Cord Blood and CD34+

Caltag Medsystems specialises in procuring haematopoietic cells and plasma collected from healthy and diseased donors. Our suppliers are able to isolate and purify a wide selection of human primary cells from a variety of tissues including: Cord Blood, Whole Blood, Peripheral Blood, Mobilised Peripheral Blood, Bone Marrow and Adipose.


Plasma is the liquid portion of the blood that remains once the cells are removed with added an anticoagulant to prevent clotting. It is comprised of water, salts, enzymes, antibodies, amino acids, hormones and other proteins. Some of these proteins are important bio-makers which could help make preventative and personalised treatments. We can provide fresh or frozen plasma from health or diseased donors as single units or pool. The donor profile pool range from pregnant, rheumatoid arthritis, lung cancer, advanced stage Alzheimer’s, lupus, prostate cancer and more.

Cord Blood and CD34+

Cord blood is used increasingly on an experimental basis as an alternative source of stem cells that are otherwise obtained from bone marrow. Cord blood is the blood that remains in placenta and umbilical cord after birth and is collected to harvest stem cells that can be used to treat hematopoietic and genetic disorders. Cord blood contains all components of whole blood (erythrocytes, platelets, leukocytes and plasma) and is also very rich in CD34+ hematopoietic stem cells (HSC). CD34+ cells are isolated from cord blood using positive immunomagnetic separation techniques. Typically 1–4 million CD34+ cells can be collected per cord.

We can provide fresh cord blood and frozen cord blood plasma. Fresh cord blood volumes range from 40-80mL per cord and are shipped using a specialised courier service
