The nonhistone nuclear protein alarmin high-mobility group box 1 protein (HMGB1) has been detected extranuclearly in muscle biopsies from patients with IIMs.
There are the antibody of the Abcam to identify this protein by different techiniques: IHC-P, ELISA, WB.
The link of the page which there is the datasheet of this antibody is: http://www.abcam.com/HMGB1-antibody-J2E1-ab80246.html#HMGB1-Primary-antibodies-ab80246-1.jpg
Hi Karoline, thank you for answer, I need to detect HMGB1 on frozen sections of human muscle biopsy by immunohystochemistry. Do you know if the antobody by abcam work on the tissue? best regards
