1. A biomarker antibody for detection of neurodegenerative diseases and pathologies associated with tau protein, comprising:
a light chain variable region having at least 85 percent of sequence identity to SEQ ID NO: 2 comprising an LCDR1 set forth in SEQ ID NO: 4, an LCDR2 set forth in SEQ ID NO: 6, and an LCDR3 set forth in SEQ ID NO:8; and
a heavy chain variable region having at least 85 percent sequence identity to SEQ ID NO: 10 comprising an HCDR1 set forth in SEQ ID NO: 12, an HCDR2 set forth in SEQ ID NO: 14, and an HCDR3 set forth in SEQ ID NO:16,
wherein said antibody detects high molecular weight variants and a low molecular weight variants of tau protein, wherein the high molecular weight variants of tau protein are greater than 70 kDa and the low molecular weight variants of tau protein are less than 70 kDa.
