What were the Western blot conditions used for the blot on the datasheet? |
|||||||||
ANSWER: |
Thank you for your enquiry. The membrane used was 0.45micron nitrocellulose, blocked in 5% non fat milk in TBS, antibody incubations in TBS +0.1% tween 20, ab7255 conc was equivalent of 1:500 from our standard tissue culture supernatant prep and incubation time was 1hr at RT with shaking. Detection in this case was with Goat anti-mouse alkaline phosphatase conjugate and development was with BCIP/NBT. The blot was made quite a while ago, probably about 1993, and if we were doing it today we would use chemiluminesnce and probably 1:1,000 to 1:2,000 ab concentration. I hope this information helps. Please do not hesitate to contact us again if you need anything further. |

Hi, I'm interested in finding a good NF-L antibody. I am curious about the amount you reccomend using for immunoblotting (i.e. what kind of dilution, 1:1000, 1:200, 1:5000, etc. etc.) Normally the data sheet indicates this information, but I did not see it there. Thanks. |

ANSWER: |
Dear Sir/Madam: Our anti-NF-L monoclonal antibody (catalog# NB 300-132) isunpurified mouse ascites (50 ul). We suugest a working dilution of 1:1,000 for ECL. Best Regards, Kate Lynott |

IHC image of ab7255 staining in human hippocampus 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 ab7255, 1µg/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.
