Anti-HTT / Huntingtin antibody IHC of human brain cerebellum. Immunohistochemistry of formalin-fixed, paraffin-embedded tissue after heat-induced antigen retrieval. Antibody LS-B36 concentration 20 ug/ml.
Anti-Huntingtin pS421 Antibody - Western Blot. Western blot analysis after AKT and phosphatase treatment is shown using Affinity Purified anti-Huntingtin pS421 antibody. In A) untreated lysates from N2A and 293A cells were stained directly using anti-Huntingtin pS421 antibody. Full length staining of Huntingtin is noted, albeit at low levels of expression, as well as a strongly staining band at 200 kD that may represent staining of truncated protein. In B) staining is shown after immunoprecipitation using a monoclonal antibody (Mab2166) followed by AKT treatment (to phosphorylate), along with untreated, and phosphatase (PP) treated (dephosphorylate) immunoprecipitated. Full length phosphorylated huntingtin is clearly detected in these immunopurified samples (except dephosphorylated). In C) lysates are treated directly with AKT or PP to alter the phosphorylation status of Htt. Personal communication, Simon Warby, CMMT, Vancouver, BC.
Anti-Huntingtin pS421 Antibody - Western Blot. Western blot analysis is shown using Affinity Purified anti-Huntingtin pS421 antibody to detect endogenous protein present in an unstimulated human PC-3 whole cell lysate (arrowhead). Comparison to a molecular weight marker indicates a band of ~190 kD corresponding to truncated human Huntingtin protein. The blot was incubated with a 1:1000 dilution of the antibody at room temperature followed by detection using standard techniques. Personal communication,.
