  • Function

    NAD-dependent oxidoreductase with broad substrate specificity that shows both oxidative and reductive activity (in vitro). Has 17-beta-hydroxysteroid dehydrogenase activity towards various steroids (in vitro). Converts 5-alpha-androstan-3-alpha,17-beta-diol to androsterone and estradiol to estrone (in vitro). Has 3-alpha-hydroxysteroid dehydrogenase activity towards androsterone (in vitro). Has retinol dehydrogenase activity towards all-trans-retinol (in vitro). Can convert androsterone to epi-androsterone. Androsterone is first oxidized to 5-alpha-androstane-3,17-dione and then reduced to epi-andosterone. Can act on both C-19 and C-21 3-alpha-hydroxysteroids.
  • Tissue specificity

    Detected in liver and prostate (at protein level). Detected in adult liver, lung, brain, placenta, prostate, adrenal gland, testis, mammary gland, spleen, spinal cord and uterus. Detected in caudate nucleus, and at lower levels in amygdala, corpus callosum, hippocampus, substantia nigra and thalamus. Detected in fetal lung, liver and brain.
  • Sequence similarities

    Belongs to the short-chain dehydrogenases/reductases (SDR) family.
  • Cellular localization

Thank you for your response and for attaching the Western blot images.

There is a clear difference in the banding pattern between cell prepared with RIPA buffer and those with Laemmli lysis buffer. This highlights the importance of use of proteinase inhibitors in the lysis buffer during sample preparation to prevent protein degradation.

On the left image (when RIPA used), there is a distinctive single band in liver tissue lysates and a double band in the PC3 cell lysate just below 50 kDa. This may well be the signal for HSD17B6. The shift between the expected band size (36 kDa) and the actual size (48 kDa) is very likely due to post-translational modification (i.e. glycosylation).

On the right image (Laemmli), in some lanes there are hardly any visible bands or bands appear at lower size 26 kDa than the expected theoretical size.

Swiss-Prot database, the predicted band size of HSD17B6 is 36 kDa. However, it is important to emphasize that there are 3 potential N-glycosylation sites at 161, 215 and 256 aa along the polypeptide chain. You can find some further information about the processed protein at this site:


I hope this helps and if I can assist further, please do not hesitate to contact me.

Thank you for your enquiry regarding ab62221 and for taking the time to provide some useful details of the experiments. I am very sorry to hear that you are having problems with this antibody.

As our Abpromise indicates, in the event that a product is not functioning in the applications/species cited on the product data sheet (and the problem has been reported within 6 months of purchase) we will happily offer a credit note/refund to the value of the product purchased.

After reading through the detailed protocol you kindly forwarded to Abcam, I would like to make the following comments/suggestions:

1) Band size:

According to Swiss-Prot database, the predicted band size of HSD17B6 is 36 kDa, you can find some further information about the processed protein at this site:


2) Lysis buffer:

It may well be that the target protein is degraded during sample preparation since no proteinase inhibitors have been used the lysis buffer. RIPA buffer is recommended to use for lysing the cells/tissues which contains a cocktail of different proteinase inhibitors to prevent any unwanted degradation. The recipe of the RIPA buffer can be found under our Protocol site:


3) Optimization:

3.a Loading different amount of protein i.e. 15, 20,25 ug per lane would be worth trying to see if the signal is getting stronger or not.

3.b Testing diffrent dilutions of primary antibody i.e. 1/500 or 1/250

3.c HSD17B6 is expressed in microsomal and early endosomal membranes, so it would be worth using membrane enriched lysates - instead of whole tissue lysates.

4) Loading control:

It would be worth running a loading control to make sure that the sample preparation and the loading was sufficient.

I hope this will be useful for you. Should you still have any problem with this antibody after following these suggestions, then please do not hesitate to contact our Technical Department again.
