Detailed explanation-1: -The Rhesus factor, or Rh factor, is a certain type of protein found on the outside of red blood cells. People are either Rh-positive (they have the protein) or Rh-negative (they don’t have the protein). This is important when you’re Rh-negative and pregnant with a fetus who’s Rh-positive.
Detailed explanation-2: -The Rh factor is an inherited protein that can be found on the surface of the red blood cell. If your blood type is positive, then your blood cells have the Rh protein. If your blood type is negative, then your blood cells lack the Rh protein.
Detailed explanation-3: -There are 5 main Rh antigens on red cells – C, c, D, E, e. The most important of these is the Rh D. Having the D antigen on the red cell gives you the positive (+) and lacking it gives you the negative (-) after the letter A, B, AB or O.
Detailed explanation-4: -The Rh factor is an inherited protein that can be present on the surface of RBCs. There are five main Rh antigens on RBCs, of which the most important is the Rh D antigen. The Rh D antigen is the most immunogenic, meaning that it may provoke an immune response.
Detailed explanation-5: -The Rh antigens are expressed as part of a protein complex in the RBC membrane. This complex is only expressed in cells of the erythroid line, and therefore Rh antigens are only expressed in RBCs.
