- The pair can be used in variety of assays and platforms including but not limited to:
- - Sandwich ELISA
- - FRET/TR-FRET/HTR
- - Meso Scale Discovery® (MSD®)
- - Luminex® and bead-based assays
- - AlphaLISA®/AlphaScreen®
- - DELFIA® immunoassays
- - Simoa® and Single Molecule Counting (SMC™) immunoassays
- - Multiplex
- Our antibody pairs are supplied in a carrier-free format that is conjugation-ready:
- - Buffer free of BSA, sodium azide, and glycerol for higher conjugation efficiency.
- - Concentration of ~1 mg/ml as measured by the protein A280 method.
- Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with
- We can label antibodies for you: get in touch today to discuss how we can help accelerate your assay development with custom conjugation services.
- Pairs are screened in biological samples, including plasma and serum, to ensure specificity in complex samples.
- Please note:
- The recommended antibody orientation is based on internal optimization in sandwich ELISA. Antibody orientation is assay dependent and needs to be optimized for each assay type.
- The range provided for this antibody pair is based on initial sandwich ELISA validation data using recombinant protein. Performance and range of the antibody pair will depend on the specific characteristics of your assay, including standard protein selection.
- We guarantee the product works in sandwich ELISA, but we do not guarantee the sensitivity or dynamic range of the antibodies in other assays.

Function
Functions in the early steps of protein synthesis by forming a ternary complex with GTP and initiator tRNA. This complex binds to a 40S ribosomal subunit, followed by mRNA binding to form a 43S preinitiation complex. Junction of the 60S ribosomal subunit to form the 80S initiation complex is preceded by hydrolysis of the GTP bound to eIF-2 and release of an eIF-2-GDP binary complex. In order for eIF-2 to recycle and catalyze another round of initiation, the GDP bound to eIF-2 must exchange with GTP by way of a reaction catalyzed by eIF-2B. -
Sequence similarities
Belongs to the eIF-2-alpha family.
Contains 1 S1 motif domain. -
Post-translational
modificationsSubstrate for at least 4 kinases: EIF2AK1/HRI, EIF2AK2/PKR, EIF2AK3/PERK and EIF2AK4/GCN2. Phosphorylation stabilizes the eIF-2/GDP/eIF-2B complex and prevents GDP/GTP exchange reaction, thus impairing the recycling of eIF-2 between successive rounds of initiation and leading to global inhibition of translation (PubMed:15207627, PubMed:18032499). Phosphorylated; phosphorylation on Ser-52 by the EIF2AK4/GCN2 protein kinase occurs in response to amino acid starvation and UV irradiation. -
Cellular localization
Cytoplasmic granule. The cytoplasmic granules are stress granules which are a dense aggregation in the cytosol composed of proteins and RNAs that appear when the cell is under stress. Colocalizes with NANOS3 in the stress granules (By similarity). - Information by UniProt
