Recombinant Mouse Antibody (3B5H10) is capable of binding to PolyQ Tract. 3B5H10 recognizes a species of htt in neurons that predicts neurodegeneration better than all other α-htt antibodies tested, including the "linear lattice"-recognizing antibody MW1.
Figure 1 mAb 3B5H10 binds low molecular weight disease-associated polyQ expansions.
3B5H10 preferentially labeled striatal neurons transiently expressing disease-associated polyQ expansions in an exon1 fragment or full-length htt. Scale bar=10 μm.

Figure 2 3B5H10 recognizes disease-associated polyQ expansions in other neurodegeneration-causing proteins.
HEK293 extracts containing HA epitope–tagged androgen receptor (AR) was blotted with 3B5H10 and α-HA or α-GST antibodies, respectively. 3B5H10 preferentially recognized versions with disease-associated polyQ expansions.

Figure 3 A species of htt recognized by 3B5H10 best predicts striatal neurodegeneration.
The significance to neurodegeneration of htt species formed in situ and distinguished by 3B5H10 was assessed by Cox analysis with a hierarchical Bayesian statistical approach. Cox coefficient (β) distribution for 3B5H10.

Figure 4 Epitope recognized by 3B5H10 is preferentially present in low molecular weight htt species.
A solution of Httex1-Q53 was chemically cross-linked and probed with MW7 or 3B5H10. MW7 staining confirms the presence of monomers and small oligomers. The epitope 3B5H10 recognizes is preferentially present in monomers over small oligomers.

Figure 5 mAb 3B5H10 binds low molecular weight disease-associated polyQ expansions.
Striatal neurons transfected with Httex1-Q46-eGFP was labeled with Alexa 647-conjugated 3B5H10 antibody.
