4-(Difluoromethoxy)-3-(trifluoromethyl)benzoic+acid
Supplier:
Bachem Americas
Description:
Isoacyl dipeptides have been developed as building blocks for preventing aggregation of the growing peptide chains during Fmoc-SPPS. As the isopeptide structure is not affected by the final acidolytic cleavage the solubility of the crude product is improved facilitating the subsequent purification. The depsipeptide will rearrange yielding the desired product in slightly basic solution.

Description:
ACTH (1–17), and aMSH (a-Melanotropin), both derived from POMC (proopiomelanocortin) are involved in melanogenesis. However, ACTH (1-17) has been found to be more potent in malanogenesis in human malanocytes. Both ACTH (1-17) and aMSH also increase dendricity, and proliferation in follicular melanocytes.

Nε-(tert-butoxycarbonyl)-Nɑ-[(9H-fluoren-9-ylmethoxy)carbonyl]-D-lysine 98%
Supplier:
Anaspec Inc
Description:
Proteins interactions with reactive oxygen agents may result in covalent modifications of amino acid residues in proteins, formation of protein-protein cross-linkages and oxidation of the protein backbone resulting in protein fragmentation. Oxidation targets for Aß(1-16) are the histidine residues coordinated to the metal ions. Copper is bound to Aß in senile plaque of Alzheimer’s disease with Aß (1-16) taking part in the coordination of the Cu2+ ions. Cu2+ and Zn2+ are linked with the neurotoxicity of Aß and free radical damage.

Description:
A bifunctional cross-linker for PEGylation. PEG polymers offer numerous favorable characteristics including high water solubility, high mobility in solution, lack of toxicity and immunogenicity, and ready clearance from the body. Thus, the chemical modification of biologically active compounds, such as peptides, antibody fragments, enzymes, or small molecules with polyethylene glycol chains (referred to as “PEGylation”), is an effective method to tailor molecular properties to particular applications.

Supplier:
Bachem Americas
Description:
Intramolecularly quenched fluorescent substrate containing the ortho-aminobenzoyl (Abz) / N-(2,4-dinitrophenyl)ethylenediamine (EDDnp) groups as the donor / acceptor pair. It corresponds to the Swedish-mutated (JMV2236) β-amyloid precursor protein (βAPP) sequence targeted by β-secretase BACE (β-site APP-cleaving activity). This FRET substrate is more selectively cleaved by BACE1 and BACE2 than by cathepsin D, a disintegrin and metalloprotease 10 (ADAM10), tumor necrosis α-converting enzyme (TACE), presenilin-1 (PS1), or presenilin-2 (PS2).
