We purchased the antibodies ab1997 and ab39178 for my experiments. I can detect bands for the mouse AD10 proteins (wt or mutants I made) but I have problems interpreting my data with ab39178. I need to know with region of the propeptide was used as immunogen, in order to build hypotheses on the "what's going on with these mutants?". Due to the mutations, I theoretically have a different maturation than for wt-AD10 but I couldn't see any differences in the WB [my constructs are fully sequenced]. |

ANSWER: |
I'm afraid I am unable to provide the exact immunogen sequence for this antibody as it is not made by Abcam and the supplier, for commercial reasons, cannot release it to us. I can tell you that the sequence is in the middle of the propeptide sequence, within the range of amino acids 80 - 120. I'm sorry I cannot help you more on this occasion. |

re ab1997 polyclonal rabbit anti ADAM 10: does this antibody a) x react with bovine ADAM 10 , I know it says the sequence is the same but just wanna check and b) does it work for immunocytochemistry on either frozen or wax sections? Thanks |
|||||||||
ANSWER: |
Although this antibody has not been tested with bovine ADAM10, we predict that it will cross react as the AA sequence of the bovine peptide is 100% identical to AAs 732 to 748 of the human peptide used as the immunogen. To our knowledge, this product has not been tested in immunocytochemistry. |

ICC/IF image of ab1997 stained HeLa cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab1997, 1µg/ml) overnight at +4ºC. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
