Tau Peptide (275-305), also known as the R2 domain fragment, represents the second repeat unit of the microtubule-binding domain of the Alzheimer's tau peptide. Tau Peptide (275-305) is considered crucial in determining the biochemical characteristics of the complete tau protein.

Acetyl-Tau Peptide (273-284) amide, an acetylated fragment of the Tau peptide, acts as an inhibitor to prevent significant aggregation of Ac-Aβ(25–35)-NH2. Furthermore, it serves as a model for studying the cross-interaction between Aβ and Tau [1] [2].

Cyclin-dependent kinase 5 (Cdk5) is a serine/threonine kinase that is predominantly active in neuronal tissues. With p25 or p35, Cdk5 phosphorylates a range of proteins, including histone H1 and tau. Cdk5 Substrate acetate is a synthetic peptide (PKTPKKAKKL) corresponding to a sequence of histone H1. It is phosphorylated by Cdk5 with a Km value of 5 µM.

Tau protein (592-597), Human (TFA) is a peptide fragment of human Tau protein.

AADvac1 is a biologically active peptide functioning as an Alzheimer's Disease Peptide Vaccine, composed of Tau(294–305) conjugated to Keyhole Limpet Hemocyanin (KLH).

Acetyl-PHF5 amide is a tau peptide with amyloidogenic properties. It can undergo polymerization to form filamentous structures [1].

Microtubule-associated protein tau (26-44) is a synthetic peptide with an amino group conjugated to glutamine and a carboxyl group conjugated to lysine.

Cyclin-dependent kinase 5 (Cdk5) is a serine/threonine kinase that is predominantly active in neuronal tissues. With p25 or p35, Cdk5 phosphorylates a range of proteins, including histone H1 and tau. Cdk5 substrate is a synthetic peptide (PKTPKKAKKL) corresponding to a sequence of histone H1. It is phosphorylated by Cdk5 with a Km value of 5 μM.
