Human HTT / Huntingtin

Rabbit

Human (tested or 100% immunogen sequence identity)

IgG Polyclonal

Unconjugated

Affinity purified

Unmodified

Huntingtin pS421 Antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to an internal region near aa 400-425 of Human Huntington Disease Protein.

pSer421

This antibody is specific for phosphorylated human Huntington protein at the pS421 residue. BLAST analysis indicates 100 % homology of the immunizing sequence with Huntington homologues from chimpanzee, pig and chicken. Cross reactivity with Huntington protein homologues from mouse and rat may also occur as sequence homology varies by one amino acid residue in this sequence. Reactivity with Huntington protein from other sources is not known. Minimal reactivity is expected with the non-phosphorylated form of the protein.

• IHC
• IHC - Paraffin (10 - 20 µg/ml)
• Western blot (1:500 - 1:3000)
• ELISA (1:10000 - 1:40000)

Immunohistochemistry: LS-B36 was validated for use in immunohistochemistry on a panel of 21 formalin-fixed, paraffin-embedded (FFPE) human tissues after heat induced antigen retrieval in pH 6.0 citrate buffer. After incubation with the primary antibody, slides were incubated with biotinylated secondary antibody, followed by alkaline phosphatase-streptavidin and chromogen. The stained slides were evaluated by a pathologist to confirm staining specificity. The optimal working concentration for LS-B36 was determined to be 10-20 ug/ml.
