The loss of all four alpha genes is termed Hb Barts hydrops fetalis (Hb Barts is a tetramer of fetal gamma globin chains).
This is the first study to report the presence of (-)-epicatechin, (+)-catechin, chlorogenic acid, and procyanidins represented in dimers, trimers, and tetramers in the tejocote (Crataegus pubescens) fruits in important concentrations in order to consider such fruit as a potential source of extraction of such polyphenols to be used in the food or nutraceutical industries.
The error bars showed the significant statistics, and control tetramer staining showed total negative (data not shown).
The findings showed that K-80003 creates a configuration that locks the tetramer into a tight ball, hiding all of its binding sites so it cannot trigger the PI3K pathway.
"Only the tetramer structure had the correct number of exposed nitrogens to bind with the sodium," says Bettinger.
Our laboratory has characterized a family of peptides know as Peptide Inhibitor of Complement C1 (PIC1) that inhibit the classical pathway of complement by binding the initiator molecule C1q and inhibiting activation of the cognate serine protease tetramer C1s-C1r-C1r-C1s that is normally associated with C1q [7, 8].
A user might want to further refine the query results to find out if those CD8+ T cell epitopes have been shown to work as tetramers or if tetramers have been made and shown to be effective.
Thus, the initial "mass" continues to exist in the PWN with its components changing to dimer, trimer, tetramer, ...: at every moment, such dimer, trimer, ..., and hexamer contained in the unit variables coexist.

Dinitrogenase, also referred to as the MoFe protein or component 1 is a 220- to 240-kDa tetramer of the nifD and nifK gene and Dinitrogenase reductase, also referred to as the Fe protein or component 2, is a 60- kDa dimer of the product of the nifH gene, which is responsible for nitrogen fixation.
