Tested Applications

• Positive WB detected in: K-562 cells, HT-1080 cells, HeLa cells, L02 cells
• Positive IHC detected in: human colon cancer tissue; Note: suggested antigen retrieval with TE buffer pH 9.0; (*) Alternatively, antigen retrieval may be performed with citrate buffer pH 6.0

Recommended dilution

• Western Blot (WB): WB : 1:500-1:2000
• Immunohistochemistry (IHC): IHC : 1:50-1:500

It is recommended that this reagent should be titrated in each testing system to obtain optimal results.

Background Information

Ei24 is an ER-localized protein originally identified as a p53-induced proapoptotic gene in etoposide-treated NIH3T3 cells. It has been shown to be able to bind to the antiapoptotic protein Bcl-2 (PMID: 15781622), play a role in autophagy (PMID: 23074225), and induce proliferate arrest/apoptosis (PMID: 10594026). Ei24 can bind specifically to IMPβ1 and IMPα2 to impede their normal role in nuclear import (PMID: 24821838).
