  • FunctionStructure-specific DNA repair endonuclease responsible for the 5'-incision during DNA repair.
  • Involvement in diseaseDefects in ERCC1 are the cause of cerebro-oculo-facio-skeletal syndrome type 4 (COFS4) [MIM:610758]. COFS is a degenerative autosomal recessive disorder of prenatal onset affecting the brain, eye and spinal cord. After birth, it leads to brain atrophy, hypoplasia of the corpus callosum, hypotonia, cataracts, microcornea, optic atrophy, progressive joint contractures and growth failure. Facial dysmorphism is a constant feature. Abnormalities of the skull, eyes, limbs, heart and kidney also occur.

Thank you for contacting us.

The lab has contacted me today regarding ab43. They have said that the information they gave me yesterday was wrong and that this antibody has indeed been tested in IP and therefore is guaranteed to function. Read More

Thank you for contacting us.

I have contacted the lab regarding the protocol used to do IP for ab43. Unfortunately, I have found out that we have no information regarding how this antibody functions in IP and therefore we cannot guarantee th...

Thank you for your reply and for kindly providing the further information.

The following secondaries detect mouse IgG2a, and are tested in WB and conjugated to HRP. I can recommend to review the online datasheets for further information. Read More

Thank you for your enquiry.

I can confirm that ab43ERCC1 antibody [3H11] is a mouse monoclonal,IgG2a isotype.

The ab97240 secondary antibody detects mouse IgG1 isotype, so it would not be suitable for use with ab43. You will need ...
