This product is not charcoal-stripped or hormone-depleted. As a human serum product derived from pooled male plasma from blood group AB, this product may contain naturally occurring levels of estradiol and progesterone. Concentrations of estradiol and progesterone are not listed as tested specifications and are therefore not provided.

Application
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.
Human Serum has been used: as a component of phosphate-buffered saline with Tween® detergent (PBST) in bridging enzyme-linked immunosorbent assay (ELISA), as a mock biological sample for assessing the performance of paper-based ELISA assay with complex biological samples, as a diluent to create a dilution series of the baseline sample for the generation of standard curve for NISTmAb spiked into serum, as well as for multiple myeloma (MM) patient sample MM2232
Biochem/physiol Actions
Human AB serum is typically obtained by allowing whole blood to clot naturally, which is known as Off-The-Clot (OTC) serum. Human serum obtained from clotted whole blood is preferred as it usually contains higher levels and a more diverse range of growth factors for optimal cell growth. Human serum from blood-type AB donors lacks antibodies specific for both A and B blood-type antigens. This makes it a universal donor serum that is suitable for various cell culture types including human stem cell lines.
Packaging
Packaging may vary for different batches due to short supply of the bottles used to pack this product. The presence or lack of shrink wrap around the cap of the bottle doesn’t impact product integrity/sterility of the product.
Analysis Note
Endotoxin tested
Other Notes
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.

Disclaimer
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.

Is this product obtained from healthy individuals? I noted that each donor unit used in the preparation was tested and found negative for HBsAG, HIV and etc. However, does each donor was tested for any underlying diseases like Diabetes and medically fit?
1 answer-
This serum product is pooled from multiple donors. Typical pooled batches range from 50 – 70 donors, but large batches may have up to 200. The general health and/or underlying condition information is not collected from individual donors. Based on electrophoresis studies, the pooled final product may be considered ‘Normal’ serum.

Is this serum contain Uric acid? If yes how much, or how to check it?. If the serum is expired, is it okay to use?
1 answer-
While uric acid is present in human serum, this product is not tested for uric acid levels. Should uric acid measurement is required, see product MAK483, Uric Acid Assay Kit, which is suitable for the determination of Uric acid in serum. It is not recommended to use products that are beyond the assigned expiration date.

IgG
10.69 – 12.04 g./L
IgA
1.32 – 2.34 g/L
IgM (not age dependent)

Il prodotto è stato testato per negatività a HSV?
1 answer-
Each donor is tested for and found non-reactive to Hepatitis B & C and non-reactive to Human Immunodeficiency Virus (HIV) antibody by ELISA. HSV is not on the list of agents that are tested. Nevertheless, products of human origin should be considered potentially infectious and handled accordingly.

If this is "serum" derived from "plasma" the plasma would have contained anti-coagulant. To turn the plasma into serum it has to be clotted. Has this product been clotted to remove the fibrin? Or is it still in fact plasma?
1 answer-
The product has been clotted. Blood is collected and treated with citrate (anticoagulant) which inhibits clotting initially. The blood is then centrifuged. When the spin is complete, layers will appear which allow a differentiation between the cells and the plasma. The plasma is removed and calcium is added to activate the clotting cascade. The preparation is then centrifuged again and the result is a large clot which is pelleted to the bottom of the tube with a serum layer on top.
