We can't recommend a particular antibody, but we list many sources for anti-MMP13 that are supposed to x-react with human and rat for IHC. Just search here:http://www.linscottsdirectory.com/search/antibodies for MMP13 (you can filter for IHC and rat reactivity) and follow "More Info" links for suppliers' data sheets. Hope this helps.
I recommend a free antibody database at labome.com. For antibodies to MMP13 you can check the following link: https://www.labome.com/review/gene/human/MMP13-antibody.html. Invitrogen MMP13 antibody (Lab Vision Corp, VIIIA2) was used in immunohistochemistry - paraffin section on human samples at 1:20 (fig 6) (Salaün et al, PLoS One. 2015). This antibody is also suitable for immunohistochemistry on rat samples. EMD Millipore MMP13 antibody (Chemicon, MAB13424) was used in immunohistochemistry - paraffin section on human samples at 5 ug/ml (Nkyimbeng et al, PLoS One. 2013). In addition, EMD Millipore has another MMP13 antibody (Chemicon International, MAB3321) used in immunohistochemistry - paraffin section on human samples at 1:1000 (Hasegawa et al, Arthritis Res Ther. 2013). R and D Systems MMP13 antibody (R&D Systems, MAB511) was used in immunohistochemistry - frozen section on human samples at 25 ug/ml (Nkyimbeng et al, PLoS One. 2013). You can find the information for these antibodies and the references following the provided links.
