We used the anti-HSD3beta-1 antibody, rabbit polyclonal from Aviva System Biological to probe 3-beta HSD1 in lysates of human prostate cancer cell lines. Compared to other vendors, this antibody from Aviva works better. The antibody does generate non-specific bands along with the 42 kDa band for 3-beta HSD1. Conditions for gel run and membrane washing can be standardized to improve the quality of Western blot data. We published an article in 2016 containing data that utilized this antibody.

|How do Aviva's reagents play a role in your experimental goals?||The antibody was utilized to detect the protein in monkey brain tissue. Giving the high homology between monkey and human sequences of the protein, we were able to specifically detect a low level of the targeted enzyme by western blot. We are now confident to utilize the ARP41821 antibody for immunohistrochemistry work to detect the spatial distribution of the enzyme in monkey brain tissue.|
|How would you rate this antibody on a scale from 1-5 (5=best) nad why?||5|
|Would you use this antibody in future experiment?||Absolutely. It will now be tested for IHC work once again in monkey brain tissue.|
|Have you used another antibody which has worked in your application?||Yes. Homemade rabbit polyclonal antibody which as revealed to be somewhat unspecific.|
|Do you believe the information about the reagent on Aviva's website is correct?||Yes|
|If the antibody works, do you plan to use it in future experiments or to publish your data? Why or why not?||If it now works in IHC in monkey brain tissue (paraffin), we will undoubtedly publish the results.|
|How did you store the antibody after re-suspension?||After resuspension at 0.2 mg/mL, it was kept at 4 degree Celsius.|
|Sample Description (please include 1) species type, and 2) cell/tissue type, and 3) how much protein loaded for each lane of your gel):||Normal monkey (cynomolgus) brain tissue. 50ug of total protein were loaded per well.|
|How many different experimental trials were conducted using the antibody sample?||Only one.|
|How was this sample prepared?||Total proteins were quantified and the sample was diluted in Laemmli buffer. 50ug of proteins were migrated on a SDS-PAGE gel.|
|Primary antibody dilution and incubation time:||1/200 in 2.5% milk buffer. Incubation overnight at 4 degree Celsius.|
|Secondary antibody used and dilution and incubation time:||HRP-conjugated goat anti-rabbit. 1/10000 in 2.5% milk buffer. Incubation room temperature 1 hour.|
|What controls were used in your experiment (positive/negative)?||Negative. Membranes blotted using only secondary antibody. Revealed no unspecific staining by the secondary antibody.|
|Please include your detailed WB Procedure/Protocol here:||A mid-brain coronal cut was done with a snap frozen bloc of cynomolgus brain tissue utilizing a cryostat. The slice weigh
was 100ug. Total proteins were extracted with lysis buffer (6M urea, 20 mM Tris pH 6.8 and 1% SDS). After protein
quantification, samples were diluted in 2X laemmli buffer. 50ug of proteins were migrated on a 10% acrylamide SDS-PAGE gel (70V for 3 hours) and then transferred on a PVDF membrane (100V for 1 hour). The membrane was then incubated with the primary and HRP-secondary antibodies as described previously before being incubated for 1 min with Bio-Rad Clarity™ Western ECL Substrate before being revealed on film (10 min exposition). Membrane was washed 3 times/10 min each in 0.05% NP40-Tween20 buffer after primary and secondary antibody incubations.
