Electrophoresis:

SDS-PAGE image of Tau Protein Marker. The seven Tau isoform proteins from top to bottom are: Tau-441, Tau-410, Tau-412, Tau-381, Tau-383, Tau-352 and Tau-316.

Purity:

>90% by densitometry on Coomassie blue stained SDS-PAGE.

Concentration:

50ng/ul of each isoform protein

Storage, Stability and Shipping:

Store product at -20^oC. For optimal storage, aliquot buffer into smaller quantities after centrifugation and store at recommended temperature. For most favorable performance, avoid repeated handling and multiple freeze/thaw cycles.
