Human AB serum is used in tissue engineering, transplantation and cell therapy applications for the expansion of mesenchymal stem cells (MSC) from adipose tissue or mesenchymal stromal cells from human bone marrow; for standardized limbal epithelial stem cell graft generation and transplantation; for ex vivo expansion of NK cells from peripheral blood in Hematopoeitic Stem Cell Expansion Medium; and for upgrading pretransplant human islet culture technology.


Each donor is tested for and found non-reactive for Hepatitis B & C and non-reactive for Human Immunodeficiency Virus (HIV) antibody by ELISA. Nevertheless, products of human origin should be considered potentially infectious and handled accordingly.




It is not unusual for our human serum products to be cloudy. This product is from pooled serum and cloudiness indicates that lipids are present in the serum. No clear, lipid-free human serum products are available.

  5. What is the difference between human serum from AB plasma and  human serum from AB clotted whole blood?

    Product H6914 is prepared from whole blood that is allowed to clot, centrifuged and the serum removed. There is no additional processing required.Product H4522 is prepared from anticoagulated (sodium citrate) whole blood. This is centrifuged to pellet the cells (RBC, WBC, some platelets) and the plasma is removed. This plasma is then treated with calcium to activate the clotting cascade. The preparation is centrifuged again and the supernatant is removed. This product can also be called plasma derived serum.Product H6914 will contain more growth factors since it is allowed to spontaneously clot and there will be the release of growth factors from many of the cells (WBC, platelets) present.  The cells are removed before the plasma is clotted for Product H4522, so this plasma will have fewer growth factors present (more similar to what is circulating). Unless testing for growth factors, most researchers are looking for Product H6914.We offer both products heat inactivated.Product H5667 Human Serum Heat Inactivated, from male AB clotted whole bloodProduct H3667 Human Serum Heat Inactivated, from human male AB plasma

Type 2 Innate lymphoid cells (ILC2s) are implicated in helminth infections and asthma where they play a role in the production of Th2-type cytokines. ILC2s express the IL-33 receptor and are a major cell type thought to mediate the effects

BACKGROUND.: The original Edmonton protocol used fresh islets, but for obvious logistic advantages most transplant centers have implemented pretransplant culture in human albumin. The aim of this study was to improve current pretransplant human islet culture techniques. METHODS.: Clinical-grade purified

Altered oncogene expression in cancer cells causes loss of redox homeostasis resulting in oxidative DNA damage, e.g. 8-oxoguanine (8-oxoG), repaired by base excision repair (BER). PARP1 coordinates BER and relies on the upstream 8-oxoguanine-DNA glycosylase (OGG1) to recognise and excise
