H-Ile-Phe-OH is a β-amyloid inhibitor that has been synthesized to interact with the amyloid protein. It is a peptidic molecule and may be able to inhibit the aggregation of amyloid proteins. This could be beneficial for the treatment of Alzheimer's disease and other neurodegenerative diseases. H-Ile-Phe-OH has been shown to have chemotactic activity, which may be due to its ability to interact with the bacterial cell wall and cause it to release chemotactic substances. This molecule has also been shown to normalize birefringence in Caco-2 cells, which may be due to its ability to stabilize actin cytoskeleton strands.

Cellulose synthase is a crucial enzyme involved in the synthesis of cellulose. Cellulose is an aggregation of unbranched polymer chains made of β-(1-4)-linked glucose residues, and is a component of primary and secondary cell walls - functioning to primarily maintain strength and shape in cells.Cellulose is synthesised by large cellulose synthase complexes (CSCs), which consist of synthase protein isoforms (CesA) that are arranged into a unique hexagonal structure.Specifically the isoform cellulose synthase 7 takes part in secondary cell wall cellulose synthesis.

The recombinant human cytidine monophosphate kinase 1 (CMPK) enzyme is a peptide with an N-terminal His tag. The enzyme is activated by ATP and phosphorylates the 3' carbon of cytidine monophosphate to form CMP. CMPK is also inhibited by a number of ligands, including adenosine, AMP, and guanosine. It has been shown that the binding of these ligands to CMPK affects ion channel activity in cells. This recombinant human CMPK enzyme is used in research as a tool for investigating protein interactions and pharmacological responses.

Ac-Lys-Thr-Lys-Gln-Leu-Arg-AMC is a peptide that is used as a research tool in the study of protein interactions. Ac-Lys-Thr-Lys-Gln-Leu-Arg-AMC binds to the acetylcholine receptor (AChR) at the interface between two subunits, which inhibits the formation of ion channels and blocks neurotransmission. This peptide has been shown to be a potent inhibitor of AChR activation by nicotinic agonists, such as acetylcholine (ACh), nicotine, and carbachol. Acetylcholine binding to AChRs induces conformational changes in the receptor that are transmitted across the synapse to activate postsynaptic receptors on muscle cells. Acetylcholine binding triggers an allosteric change in the AChR that results in increased permeability of ion channels, leading to depolarization of

The cyclic AMP (cAMP) response element binding protein (CREB) is a transcription factor that regulates the transcription of several genes that mediate important cellular processes. CREB is phosphorylated by several kinases, including PKA- Akt- and CamK I, II, and IV. Phosphorylated pCREB translocates to the nucleus, where it forms homodimers or heterodimers, and recruits p300/CREB binding protein (CBP) to initiate transcription of its target genes. pCREB is an important regulator of apoptosis and is also involved in modulating several immune processes and neuronal plasticity. CREB signalling has a critical role in the formation of memories and may be dysfunctional in the brains of Alzheimer's disease (AD).Peptide is labelled with an N-terminal 5-carboxyfluorescein (5-FAM), a widely used green fluorescent tag.

HMGB1 is a protein that belongs to the family of high-mobility group box proteins. It is involved in regulating the release of inflammatory mediators and cytokines, such as IL-1β, IL-6, TNF-α and MCP-1. HMGB1 also plays a role in activation of neutrophils and macrophages. The recombinant form of HMGB1 has been shown to be an excellent research tool for studying protein interactions and receptor ligand interactions. High purity HMGB1 can be used as a pharmacological inhibitor or activator.
