(Hb H is a tetramer
of beta globin chains.) Hb H disease is typically a moderate hemolytic anemia associated with splenomegaly and bone changes.

However in each sub class tetramer
do not form and they bind to the red blood cell membranes, causing damage to membrane.
(26) On the other hand, MacKinnon and his group analyzed the structure of a bacterial [K.sup.+] channel, KcsA, with two transmembrane helices and a tetramer
structure, by X-ray crystallography and clearly elucidated the [K.sup.+]-selective mechanism.
* Excellent separation of oligomers--dimers, trimers, tetramers
Cells were incubated with major histocompatibility class II tetramers
containing an immunodominant peptide epitope of HKx31 (nucleoprotein, I-[A.sup.b]/[NP.sub.311-325]; NIH Tetramer
Core Facility, http: //tetramer.yerkes.emory.edu/).
Functional consequences of mutations at the allosteric interface in hetero- and homo-hemoglobin tetramers
. Protein Sci.
The three-dimensional structures reveal that MDHs are homomeric enzymes organized usually as either dimers or tetramers
with subunit molecular masses of 30-38 kDa, which have homologous active sites, cofactor-binding sites, and quaternary structures based on the sequence comparisons and bioinformatics analysis.
The technology, called "major histo-compatibility complex (MHC) tetramers
," allows scientist to follow immune responses mediated by individual T-cells.
