Abo antigens

Abo antigens

(Science: haematology, immunology) a system of genetically determined antigens (proteins) located on the surface of the erythrocyte.

The presence of these specific antigens gives a blood its unique properties. Because of the antigen differences existing between individuals, blood groups are significant in blood transfusions, maternal-foetal incompatibilities (erythroblastosis foetalis), tissue and organ transplantation.

Biological Immortality and Immortalised Cell lines

... used to generate immortalized cell lines. One method is to introduce a viral gene that partially deregulates the cell cycle, such as EBV, SV40 T antigens and HPV-16 E6/7 gene. Artificial expression of key proteins required for immortality is another approach to induce immortalization. Besides,inactivation ...

Relationship between cell lines and cancer research (IHC)

... I posted my question in the wrong section. At my current internship I am going to stain different cell lines (examples: HELAp2, COLO741, etc) with antigens (immunohistochemistry) relating to cancer research (examples p53, MSH-2/6, MLH-1, PMS-2). But I can’t seem to understand the underlying reason ...
