Human eIF2 alpha Antibody

Detection of Human eIF2 alpha by Western Blot.

Western blot shows lysates of K562 human chronic myelogenous leukemia cell line, MCF-7 human breast cancer cell line, CTLL-2 mouse cytotoxic T cell line, and NRK rat normal kidney cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human eIF2a Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3997) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for eIF2a at approximately 38 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Detection of Human eIF2 alpha by Simple Western^TM.

Simple Western lane view shows lysates of MCF-7 human breast cancer cell line, loaded at 0.2 mg/mL. A specific band was detected for eIF2a at approximately 42 kDa (as indicated) using 10 µg/mL of Goat Anti-Human eIF2a Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3997) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system. Non-specific interaction with the 230 kDa Simple Western standard may be seen with this antibody.

Detection of eIF2 alpha by Western Blot

Analysis of signal transduction during CHIKV infection in the presence of 50 nM silvestrol. (A) HEK 293T cells were seeded in six-well plates and were infected with CHIKV using an MOI of 1, and 50 nM silvestrol was added where indicated. Cells were treated with IFN alpha for 30 min before harvest if indicated, and Western blot analysis of cell lysates was performed. (−) Untreated cells; (+) treated cells. In lanes 3–6, cells were infected with CHIKV. The CHIKV E2 protein, STAT1, eIF2 alpha, and their phosphorylated proteins were detected with specific antibodies and secondary HRP-coupled antibodies, and the ECL detection system (Amersham, Freiburg). Equal loading of each blot was controlled by detection of beta-actin; and, (B) Uninfected HEK293T cells were treated with IFN alpha for 30 min before harvest and either treated with silvestrol for 16 h or left untreated. Western blot analysis of cell lysates was performed and p-STAT1 and STAT1 were detected. STAT1 served as a loading control.
