Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 36 kDa (predicted molecular weight: 33 kDa).
IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
Flow Cyt Use at an assay dependent concentration.
ICC/IF 1/100 - 1/250.
  • Application notes
    Is unsuitable for IP.
  • Target

    • Function

      Structure-specific DNA repair endonuclease responsible for the 5'-incision during DNA repair.
    • Involvement in disease

      Defects 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.

    • Flow Cytometry analysis of HepG2 (human hepatocellular carcinoma) cells labeling ERCC1 with purified ab129267 at 1/80 dilution (10ug/ml) (red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. A Goat anti rabbit IgG (Alexa Fluor® 488)(1/2000 dilution) was used as the secondary antibody. Rabbit monoclonal IgG (Black) was used as the isotype control, cells without incubation with primary antibody and secondary antibody (Blue) were used as the unlabeled control.

    Thank you for contacting us.

    I can confirm, that the ab129267 is raised against the first 160 aa and binds to the N-Terminus of the ERCC1 protein.

    The ab129093 is regrettably raised against the C-terminus of the ERCC1 protein and for that reason unlikely to be suitable for your purpose.

    I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

    Thank you for calling earlier today.

    1. For a hematoxylin stain for nuclei, you will need your hematoxylin solution, which I am assuming is ready-to-use, and a 1% solution of "acid alcohol". This is prepared by simply adding 1 ml of HCL to 99 ml of 70% ethanol. (Use full-strength, 37%, HCl also referred to as 12N. Be careful with this! Use only in a fume hood).

    2. Incubate the sections in the hematoxylin only after they have been stained with DAB and rinsed in distilled water. 2 minutes incubation in the hematoxylin should be sufficient but it will depend on the type of hematoxylin you have. In any case, you will not need to incubate for more than 8 minutes, room temperature.

    3. Rinse in two changes of distilled water, then dip in acid alcohol solution two or three times to remove most of the stain. The nuclei should remain stained, and there may be a light overall blue stain of the rest of the section, which is OK. If there seems to be too much, you can keep dipping in the acid alcohol to remove more.

    4. Rinse in running tap water for two minutes. This needs to be tap water, not distilled, as the ions in the tap water will help develop a nice blue shade.

    5. Now you can coverslip with your aqueous mounting medium! You can practice with sections that you have not stained for ERCC1 beforehand, to make sure you get a counterstain you like. If the hematoxylin is old, it may create problems, like splotchy staining.
