Huntingtin antibody | HDC8A4
Mouse anti Huntingtin antibody, clone HDC8A4 (MCA2051) used to demonstrate perinuclear huntingtin expression and it's co-localization with the endoplasmic reticulum by immunofluorescence.
Image caption:
Confocal microscopy experiments showing that HTT proteins are enriched in the perinuclear and co-localize with the endoplasmic reticulum (ER) marker calreticulin upon treatment of Rp-cAMP or 8-pCpt2'-O-Me-cAMP (8-pCpt-cAMP). upper panels representative images showing the immunofluorescent signals of Htt (green), ER marker (red, only in the third and fourth columns) and DAPI (blue) in STHdh Q7/Q11 cells treated by vehicle, 1 μM Rp-cAMP or 1 μM 8-pCpt-cAMP. Scale bars, 20 μM. The two panels on the right side are magnified images from the left for visualizing the co-localization. Yellow pixels indicate co-localization.

Image caption:
Representative confocal microscopic immunofluorescent images of Htt and Rab39B in STHdhQ7/Q11cells. Treatment with 1 μM RP-cAMP or 1 μM 8-pCPT-2'-O-Me-cAMP for 48 hours leads to increased co-localization between Htt and Rab39B. Red: Rab39B; Blue: DAPI; Green: Htt (using antibody MCA2051); The lower panels are magnified images from the upper for visualizing the co-localization. Yellow pixels indicate co-localization. Scale bars: 20 μm. Right panels: co-localization parameters including Pearson's coefficient and overlap coefficient (mean and s.e.m.). Numbers indicate the number of cells analyzed for each treatment from 5 or more biological replicates.

No increase of Htt co-localization with Rab22A. Representative confocal microscopic immunofluorescent images of Htt and Rab22A in STHdhQ7/Q11 cells and quantitation analysis of co-localization. Treatments with 1 μM RP-cAMP or 1 μM 8-pCPT-2'-O-cAMP for 48 hours leads to no change of co-localization between Htt and Rab22A. Red Rab22A; Blue: DAPI; Green: Htt (using antibody MCA2051); Scale bars 20μm.

Mouse anti Huntingtin antibody, clone HDC8A4 reacts with an epitope corresponding to the HDC region (2703 - 2911 amino acids) of the huntingtin protein.
Mouse anti Huntingtin antibody, clone HDC8A4 detects a ~350 kDa band on western blots but also detects smaller degradation products of huntingtin. Clone HDC8A4 recognizes both denatured and native huntingtin in human brain.
The combined use of Mouse anti Huntingtin antibody, clone HDC8A4 (MCA2051) and HDB4E10 (MCA2050) demonstrate that huntingtin is enriched in neuronal cells in the brain.
