Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.
Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.
We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.
In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.
We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.
Applications & species from publications and Abreviews that have not been tested in our own labs or in those of our suppliers are not covered by the Abpromise guarantee.
Please check that this product meets your needs before purchasing.

Our Abpromise guarantee covers the use of ab190791 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/1000 - 1/10000. Detects a band of approximately 17 kDa (predicted molecular weight: 13 kDa).|
RelevanceProtamines are small, arginine-rich proteins involved in the condensation of sperm chromatin. During spermiogenesis, histones are replaced by protamines (P1 and P2), resulting in sperm chromatin condensation followed by a halt to gene expression in haploid spermatids and spermatozoa. As a consequence, protamine deficiency and aberrant P1/P2 ratio have a profound effect on both fertilization and embryo development.
