Our Abpromise guarantee covers the use of ab2179 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/1000 - 1/10000. Detects a band of approximately 170 kDa (predicted molecular weight: 159 kDa).|
|IP||Use a concentration of 1 - 4 µg/ml.|
|ICC||Use a concentration of 5 µg/ml.|
FunctionParticipates in DNA replication and repair. Exhibits a magnesium-dependent ATP-dependent DNA-helicase activity that unwinds single- and double-stranded DNA in a 3'-5' direction.
Involvement in diseaseDefects in BLM are the cause of Bloom syndrome (BLM) [MIM:210900]. BLM is an autosomal recessive disorder characterized by proportionate pre- and postnatal growth deficiency, sun-sensitive telangiectatic hypo- and hyperpigmented skin, predisposition to malignancy, and chromosomal instability.
Sequence similaritiesBelongs to the helicase family. RecQ subfamily.
Contains 1 helicase ATP-binding domain.
Contains 1 helicase C-terminal domain.
Contains 1 HRDC domain.
modificationsPhosphorylated in response to DNA damage. Phosphorylation requires the FANCA-FANCC-FANCE-FANCF-FANCG protein complex, as well as the presence of RMI1.

HeLa cells cultured on coverslips were fixed in 4% paraformaldehyde then stained with ab2179 (green) at a concentration of 5µg/ml. The DNA stained with DAPI is shown in red (100x magnification).
HeLa cells were treated with 15µM Bleomycin for 2 hours to generate DNA double stranded breaks (DSBs). Paraformaldehyde-fixed cells were co-immunofluorescently labelled with anti-gamma H2AX (DNA DSB marker) and anti-BLM (ab2179). ab 2179 was used at a concentration of 5µg/ml. Colocalization at the sites of DNA DSBs is identified by the arrows. In the final panel DAPI is pseudo-coloured blue, while anti-gamma H2AX and anti-Blm are green and red respectively.
