Tested Applications

• Positive WB detected in: MCF-7 cells, HEK-293 cells
• Positive IHC detected in: human cervical cancer tissue; Note: suggested antigen retrieval with TE buffer pH 9.0; (*) Alternatively, antigen retrieval may be performed with citrate buffer pH 6.0
• Positive IF/ICC detected in: HEK-293 cells

Recommended dilution

• Western Blot (WB): WB : 1:500-1:2000
• Immunohistochemistry (IHC): IHC : 1:50-1:500
• Immunofluorescence (IF)/ICC: IF/ICC : 1:50-1:500

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

Background Information

Chromodomain helicase DNA-binding protein 4 (CHD4) is an ATP dependent chromatin remodeler and a major subunit of the repressive NuRD complex [PMID:9790534]. This complex plays key roles in transcriptional regulation and reorganization and maintenance of chromatin structure, as it targets pericentromeric heterochromatin and has recently been implicated in DNA damage repair, being rapidly recruited to DNA double strand breaks [PMID:17694084]. CHD4 is a novel BRIT1 binding partner that regulates the HR repair process, which is a critical pathway of repairing DNA double strand breaks and plays an essential role in maintaining genomic integrity [PMID:22219182]. The calcualted molecular weight of CHD4 is 218 kDa, but modified CHD4 is about 250-280 kDa.
