Anti-Huntingtin (Htt) antibody is a Mouse of scFv class that binds to an Huntingtin (Htt). This antibody recognizes a species of htt in neurons.
Figure 1 Higher temperature sensitivity of the Q25 TR-FRET signal is due to structural or spatial changes of HTT polyQ.
(a) Western-blots of HEK293T cells transfected with different HTT-exon1 Q25 and Q72 constructs with point mutations as indicated. The last lane on each blot is from nontransfected HEK293T lysate. (b) Temperature sensitivity of the 4C9/MW1 TR-FRET signals. All signals are normalized to the signal at room temperature (RT), n53. Q25 has higher temperature sensitivity for all the HTT-exon1 constructs with or without point mutations. (c) Temperature sensitivity of the 2B7/3B5H10 TR-FRET signals for Q25 and Q72. All signals are normalized to the signal at room temperature (RT), n56. Between 4uC and RT, Q25 has higher temperature sensitivity than Q72.

Figure 2 Monitoring disassembly of single htt aggregates incubated withMW7or 3B5H11 by in situ AFM.
Samples of HD53Q were incubated for 6–8 h after removal of the GST moiety to form a large population of fibrils. These fibrils were deposited on mica and imaged using in situ AFM, which allows for the tracking of the fate of individual fibrils as a function of time. These fibrils were imaged in the absence or presence of anti-htt antibodies. Fibrils appeared to be stable after treatment with buffer, MW1-MW5, or MW8 (location of stable fibrils indicated by black arrows). However, treatment with MW7or 3B5H10 caused fibrils to disaggregate and/or shorten in length (location of disaggregating fibrils indicated by green arrows). Scale bar represents 500 nm and is applicable to all images.

Figure 3 Size analysis of aggregate observed with MW7 or 3B5H10 added to monomeric or fibrillar HD54Q.
A, A, HD53Q oligomers (HD53Q incubated alone) after 5 h of incubation were predominantly 4 –5 nm in height with several as tall as 6 – 8 nm. B, when MW7 was incubated (added
at t = 0 h) with monomeric HD53Q (black diamonds), the height of globular aggregates formed after 5 h of co-incubation were predominantly 3– 4 nm tall, although there was a large portion of taller globular aggregates(shoulder on the right of the histogram). In contrast, when MW7 was incubated with pre-aggregated fibrillar HD53Q (gray circles), globular aggregates (conditions where fibrils disaggregated) observed when imaged 3 h after addition of MW7 were much taller (4 –5 nm) in comparison to those formed by adding MW7 to monomeric HD53Q, with a larger portion of aggregates being 5–10 nm tall. C, when 3B5H10 was incubated (added at t = 0 h) with monomeric HD53Q (black diamonds), the majority of globular aggregates observed after 5 h co-incubation were 2–3 nm in height. Similarly, when 3B5H10 was incubated with pre-aggregated fibrillar
HD53Q (gray circles), globular species (conditions where fibrils disaggregated) observed 3 h after the addition of 3B5H10 again were predominantly 2–3 nm tall.
