DATASHEET

Host: Rabbit

Target Protein: eIF-2a (Ser51)

Modification Site: Ser51

Clonality: Monoclonal

Isotype: IgG

Entrez Gene: 83939

Swiss Prot: Q9BY44

Source: Synthetic phospho-peptide surrounding Ser51 of human eIF-2a

Purification: Purified by Protein A.

Storage Buffer: 0.01M TBS(pH7.4) with 1% BSA, 0.02% Proclin300 and 50% Glycerol.

Storage: Store at -20°C for 12 months.

Background:

Functions in the early steps of protein synthesis of a small number of specific mRNAs. Acts by directing the binding of methionyl-tRNAi to 40S ribosomal subunits. In contrast to the eIF-2 complex, it binds methionyl-tRNAi to 40S subunits in a codon-dependent manner, whereas the eIF-2 complex binds methionyl-tRNAi to 40S subunits in a GTP-dependent manner.

Size: 100µL

Concentration: 1ug/ul

Predicted Molecular Weight: 36 kDa


Cross Reactive Species: Human
Mouse
Rat
