We have had several requests for SOX11 IHC Control Slides. We have found the tissue (human) and it has breezed through Quality Control. Slides are available in boxes of 100 (98 unstained & 2 stained slides) or boxes of 25 (24 unstained & 1 stained slide). Let us know if you would like a quote. Also, please send in your requests for other hard to find control slides you want us to source. href="https://pathsupply.com/ck7-to-ihb-ihc-control-slides-12.html">https://pathsupply.com/ck7-to-ihb-ihc-control-slides-12.html
