Description: Although FITC reagents have been more often used to prepare fluoresceinated bioconjugates, the low stability of FITC bioconjugates makes some researchers use amine-reactive succinimidyl esters of carboxyfluorescein (commonly called FAM) in bioconjugations. FAM reagents give carboxamides that are more resistant to hydrolysis. We have shown that FAM reagents require less stringent reaction conditions and give better conjugation yields, and the resulted conjugates have superior stability. We noted that FITC labeled peptides tend to deteriorate more quickly than the corresponding FAM conjugates.

Description: Beta-amyloid is the main component of amyloid deposits in the AD brain. Beta-amyloid peptides have a heterogeneous C-terminus with the majority composed ofAβ1-40, while a minor product is Aβ 1-42. Additional minor Aβ peptides are also normally produced, such as Beta-amyloid 1-34, 1-37, 1-38 and 1-39, and few reports have quantified the levels of these peptides in the brain.

Description: West Nile virus (WNV) is a member of the flavivirus genus, which contains many significant human pathogens including Dengue virus (Den), Japanese Encephalitits virus (JE), and Yellow Fever virus (YF). WNV is a small, enveloped virus with a single stranded, positive sense 11kb RNA genome, which encodes a polyprotein precursor. This polyprotein must be cleaved co- and post-translationally to produce ten functional proteins: three structural (C, prM and E) and 7 nonstructural (NS1, NS2A, NS2B, NS3, NS4A,NS4B and NS5). WNV NS3 protease is absolutely essential (along with viral-encoded cofactor NS2B) for post-translational cleavage and viral replication. As a result, this protease is a potential therapeutic target.

His-tagged recombinant WNV NS3 protease (residues 1 to 184) was expressed as a fusion protein with the cofactor NS2b (residues 49 to 96) and a linker sequence (GGGGSGGGG) in E. coli. The apparent Mr on SDS-PAGE is 32-kDa. Its activity can be measured by FRET peptides

Description: This peptide is a fragment of the human aquaporin-2 (AQP2) phosphorylated at Ser261. Protein phosphorylation plays a key role in vasopressin signaling in renal-collecting duct. Phosphorylation at several AQP2 residues including Ser256 and Ser261, is altered in response to vasopressin. It is possible that both sites are involved in vasopressin-dependent AQP2 trafficking.

Description: The sequence (Accession # AAC04279.1) corresponding to the full length human Tau-441 (2N4R isoform) protein along with GST tag at N-terminal was expressed in E. coli. The recombinant GST-Tau-441 protein was purified from bacterial lysate using proprietary method.
Microtubule associated protein (Tau) is found predominantly in the central neural system and its major function is to promote assembly and to stabilize neuronal microtubules. Six isoforms of Tau were identified in humans that are differentiated by the exclusion or inclusion of exons 2, 3, and 10. Tau-441 is the longest of Tau isoforms, consisting of 441 amino acids with molecular mass of 45.8 kDa. Under physiological conditions Tau can undergo abnormal phosphorylation, truncation, or other modifications that result in the protein detachment from microtubules. These modified Tau molecules can self-associate and form different types of aggregates including neurofibrillary tangles (NFTs) found in brains of patients with neurodegenerative diseases such as Alzheimer’s disease.

Description: A dimer of CKS-17 has a natural occurring cysteine at the carboxyl terminus (where it occurs in the retroviral peptides on which CKS-17 is based) and dimerization is accomplished by cysteine-disulfide linkage. CKS-17 is a synthetic retroviral envelope heptadecapeptide corresponding to a region highly conserved in retroviral transmembrane proteins such as pl5E. The CKS-17 peptide has been previously shown to inhibit monocyte superoxide production, natural killer cell activity, polyclonal B-cell activation, and monocyte-mediated killing by inactivation of interleukin-1.
