CytoGlow™ eIF2α (Phospho-Ser51) Colorimetric Cell-Based ELISA Kit

The eIF2α (Phospho-Ser51) Colorimetric Cell-Based ELISA Kit offered by Assay Biotechnology is an innovative and user-friendly assay kit designed to detect and quantify the expression profile of Phospho-eIF2α (Ser51) protein in cells. This kit offers a range of advantages, including its convenience, high throughput capacity, and exceptional sensitivity. Moreover, it eliminates the need for lysate preparation, streamlining the experimental process and saving valuable time for researchers.

The primary application of this kit lies in its ability to precisely monitor the phosphorylation status of eIF2α at Ser51 and evaluate its expression levels in cultured cells. This capability empowers researchers to investigate the functional significance of eIF2α phosphorylation in different cellular contexts.

Beyond quantification, the Phospho-eIF2α (Ser51) Colorimetric Cell-Based ELISA Kit is also ideal for screening the effects of diverse treatments, inhibitors (such as siRNA or chemicals), or activators on eIF2α phosphorylation. This screening functionality allows for comprehensive investigations into the regulatory mechanisms governing eIF2α signaling and its impact on cellular processes.

To ensure the utmost specificity and reliability, the kit includes highly specific antibodies. The Anti-eIF2α (Phospho-Ser51) Antibody, a rabbit polyclonal antibody, has undergone thorough testing on Western Blots, revealing a single protein band detected in the presence of the immunogen peptide. This confirms the antibody’s precision in recognizing eIF2α phosphorylated at Ser51.

Excellent specificity for phosphorylated eIF2α at Ser51

The Phospho-eIF2α (Ser51) Colorimetric Cell-Based ELISA Kit demonstrates remarkable specificity, as validated through various assays. The Anti-eIF2α (Phospho-Ser51) Antibody, a rabbit polyclonal antibody utilized in the kit, was subjected to Western Blot analysis. This analysis showed the detection of a single protein band in extracts from K562 cells treated with IFN-alpha. Moreover, this protein band’s specificity was further confirmed, as it could be effectively blocked by the synthesized immunogen peptide. Similarly, in an ELISA assay, the Anti-eIF2α (Phospho-Ser51) Antibody exhibited high specificity for the phospho-peptide compared to the non-phospho peptide counterpart. These findings substantiate the antibody’s ability to selectively target and recognize phosphorylated eIF2α at Ser51.

Furthermore, the Anti-eIF2α Antibody, another rabbit polyclonal antibody, demonstrated specificity through Western Blot analysis, where a single protein band was detected in rat lung extracts. The specificity of the Anti-GAPDH Antibody, a mouse monoclonal antibody, was also validated on Western Blots using tissue lysates from human, mouse, and rat, showing detection of a single protein band in all three lysates. The stringent antibody specificity tests ensure that the Phospho-eIF2α (Ser51) Colorimetric Cell-Based ELISA Kit delivers reliable and accurate results, enabling researchers to confidently investigate the phosphorylation status of eIF2α and its potential implications in cellular processes.
