I ordered 2 vials of this antibody and was expecting to receive 200 ug, but I only received 36 ug in each vial, for a total of 72 ug. |
|||||||||
ANSWER: |
I am sorry that you did not receive the proper amount of antibody that you ordered and for the inconvenience this has caused. As requested, I have issued a free of charge replacement of 3 vials for an additional 174 ug. To check the status of the order please contact our Customer Service team and reference this number. Please note that this free of charge replacement vial is also covered by our Abpromise guarantee. Should you still be experiencing difficulties, or if you have any further questions, please do not hesitate to let us know. I wish you the best of luck with your research. |

I'll like to know if this antibody recognized all forms of histone H3 sush as the variant H3.3? Is it possible to get the amino sequence of the epitope recognized by this antibody or the amino acid sequence of the immunizing peptide? |
|||||||||
ANSWER: |
Thank you for your inquiry. Unfortunately, we are not able to release the immunogen sequence for this particular antibody as it is proprietary information. We aim to provide as much information as possible to our customers, so I am sorry that this has not been possible on this occasion. However, the homology of the immunogen and H3 variants: H3.1, H3.2, H3.3 is 100%. Should you have any further questions, please do not hesitate to contact us. |

Chromatin was prepared from Hela cells according to the Abcam X-ChIP protocol. Cells were fixed with formaldehyde for 10min. The ChIP was performed with 25µg of chromatin, 2µg of ab10799 (blue), and 20µl of Protein A/G sepharose beads. No antibody was added to the beads control (yellow). The immunoprecipitated DNA was quantified by real time PCR (Taqman approach for active and inactive loci, Sybr green approach for heterochromatic loci). Primers and probes are located in the first kb of the transcribed region.
IHC image of Histone H3 staining in human breast carcinoma FFPE section, performed on a BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab10799, 5µg/ml, for 8 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
