Study Notes
Antibodies and Blood Types
- Naturally occurring antibodies against A and/or B antigens typically consist of IgM.
- These antibodies are found in plasma of individuals with red blood cells that lack the corresponding antigen.
Rh Blood Group System
- The Rh blood group locus includes two structural genes: RhD and RhCE.
- RhD gene encodes the membrane protein that carries the D antigen, while RhCE carries Cc and Ee antigens.
- Presence of the RhD gene results in the Rh D+ phenotype, while its absence leads to the Rh D– phenotype.
