Cat.No. : EEF1A1-001H
Product Overview : Recombinant protein of human eukaryotic translation elongation factor 1 alpha 1 (EEF1A1) with C-terminal MYC/DDK tag, expressed in HEK293T cells.
Description : This gene encodes an isoform of the alpha subunit of the elongation factor-1 complex, which is responsible for the enzymatic delivery of aminoacyl tRNAs to the ribosome. This isoform (alpha 1) is expressed in brain, placenta, lung, liver, kidney, and pancreas, and the other isoform (alpha 2) is expressed in brain, heart and skeletal muscle. This isoform is identified as an autoantigen in 66% of patients with Felty syndrome. This gene has been found to have multiple copies on many chromosomes, some of which, if not all, represent different pseudogenes.

A biolayer interferometry assay on the Octet Red machine determined the association (Ka) and dissociation (Kd) constants of purified wild-type (WT) and E300R mutant HIV-1 reverse transcriptase (RT) heterodimer with biotinylated eEF1A immobilized on a streptavidin-coated biosensor. The Ka is the rate of RT complex formation with eEF1A per second in a 1 M solution, and the Kd is the fraction of complexes decayed per second. The Ka divided by the Kd is the binding affinity (KD).

The mean levels of serum EEF1A1 autoantibody (EEF1A1-AAb) by age group in type 1 diabetes mellitus patients (squares) vs. non-diabetic control subjects (circles), as measured by ELISA using recombinant EEF1A1 (OriGene TP309697). a: significantly different compared to nondiabetic control subjects in each age group (P < 0.05); b: significantly different compared to 18- to 29-year-old in each disease status (non-diabetic control group and type 1 diabetes mellitus patients, respectively; P < 0.05).

Biolayer interferometry assays (BLI) of a biotinylated HIV RTp66/p51-loaded or integrase-loaded biosensor with 60 nM of purified eEF1A, eEF1B, eEF1D, eEF1G or BSA as analytes.
