Blood Type
|
|
•Distinct molecules called antigens are attached to the surface of red blood cells.
–There are two different types of antigens, type "A" and type "B". –Each type has different properties. –The ABO blood type classification system uses the presence or absence of these molecules to categorize blood into four (really 8) types. •Another level of specificity is added to blood type by examining the presence or absence of the Rh protein. –Each blood type is either positive "+" (has the Rh protein) or negative "-" (no Rh protein). •For example, a person whose blood type is "A positive" (A +), has both type A and Rh proteins on the surface of their red blood cells. •O- is the universal donor. •AB+ is the universal receiver. |

Note: We didn't put paper in our developing chamber. I just waited about 30 minutes because I know from experience that it needs time to "saturate" the chamber with the chemicals (mobile phase) we poured into the developing chamber.
