General description

GST-tagged recombinant exon1 of wild-type human huntingtin HTTx1 (20Q) protein.

Specificity

Clone PHP4 is a mouse monoclonal antibody that detects Huntington protein. It targets an epitope within polyQ-polyP junction (QQQQPPPP). It predominantly reacts with soluble mutant HTT.

Application

Immunohistochemistry Analysis: A representative lot detected mutant HTT in Immunohistochemistry applications (Ko, J., et. al. (2018). Hum. Mol. Genet. 27(13): 2330-2343).

Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected mutant HTT in Brain tissue lysates of 6 and 9 month-old WT or Q140 KI HD mice (Courtesy of Ali Khoshnan, Ph.D., California Institute of Technology, Pasadena, CA).

Dot Blot Analysis: A representative lot detected mutant HTT in Dot Blot applications (Ko, J., et. al. (2018). Hum. Mol. Genet. 27(13): 2330-2343).

Inhibits Activity/Function Analysis: A representative lot partially blocked seeding and subsequent fibril assembly of mHTTx1 in cell culture models of HD. (Ko, J., et. al. (2018). Hum. Mol. Genet. 27(13): 2330-2343).

Western Blotting Analysis: A representative lot detected mutant HTT in Western Blotting applications (Ko, J., et. al. (2018). Hum. Mol. Genet. 27(13): 2330-2343).

Electron Microscopy Analysis: A representative lot detected mutant HTT in Immuno-Electron Microscopy applications (Ko, J., et. al. (2018). Hum. Mol. Genet. 27(13): 2330-2343).

Quality

Evaluated by Immunohistochemistry (Paraffin) in human Huntington′s diseased brain tissue sections.

Immunohistochemistry (Paraffin) Analysis: A 1:50 dilution of this antibody detected mutant HTT in human Huntington′s diseased brain tissue sections.

Physical properties

347.60 kDa calculated.

Physical form

Purified mouse monoclonal antibody IgG1 in PBS without azide.

Storage and Stability

Stable for 1 year at -20°C from date of receipt. Handling Recommendations: Upon receipt and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.
