I am expressing a series of constructs based on ADAM10 all beginning at amino acid 214 (TTSAEKN...) which is immediately downstream of the furin cleavage site. I'd like it confirmed that I will be able to pick up these derivatives with ab39153. Thank you |

ANSWER: |
Thank you for your enquiry and your interest in our products. As I have mentioned in the previous mail, the information you requested is confidential and we have no access to you. However, after check with our source, I can confirm that the epitope for ab39153 begins past amino acid 214. I hope this information will be useful for you.

The storage buffer contains 50% glycerol and 0.05% sodium azide per data sheet. Please confirm whether the buffer is "0.01 M phosphate buffered saline" per our listing. Also, please ask whether vendor has assayed the purity by SDS and whether they have a spec for purity/.

ANSWER: |
Thank you for your enquiry. The antibodies are >95% pure by SDS-PAGE. The sodium chloride concentration is 0.25 M. The phosphate concentration has changed slightly over the course of years as the peptide-affinity column elution protocol has been optimized, but it has always fallen within the range of 4 to 10 mM before adding glycerol to 50%, and is therefore 2 to 5 mM after the addition of glycerol. I hope this information helps, please do not hesitate to contact us if you need any more advice or information. |

IHC image of ab39153 staining in human normal lymph node formalin fixed paraffin embedded tissue section, performed on a Leica 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 ab39153, 5µg/ml, for 15 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.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
