Background

Recognizes a protein of 70kDa, identified as p70 subunit of Ku. The epitope of this antibody maps between amino acids 506-541 of p70. The Ku autoantigen is a heterodimer of 70kDa (p70) and ~80kDa (p80) proteins. The p70/p80 dimer is important for function of a 460kDa DNA-dependent protein kinase (DNA-PK) that phosphorylates certain transcription factors, including Sp1, Oct-1, p53, and SV40 large T antigen in vitro.

Immunogen

Hybridoma produced by the fusion of splenocytes from BALB/c mice immunized with human placental extract designated as PSE1-PL and mouse myeloma NS1 & Sp2/0 cells.

Positive Control

BT474, HeLa, human K562, HL-60, HEp-2, HeLa, Cos-1 cells
