Delta Sleep-Inducing Peptide (DSIP) is a neuropeptide that induces delta sleep in mammals. Studies have shown that DSIP plasma concentrations and the human circadian rhythm are correlated and that DSIP concentrations are dependent on the initiation of sleep. Interestingly DSIP has the ability to cross the blood-brain barrier and can be absorbed from the gut.  This neuropeptide is found in plasma, peripheral organs and neurons and its functions extend beyond inducing sleep. For example it has the ability to affect levels of hormones, neurotransmitters and psychological performance. It has also been found that schizophrenia and depression patients have lower concentrations of DSIP in their cerebrospinal fluid and plasma. Clinically DFSIP has already been used to treat opioid and alcohol withdrawal in reducing symptoms felt by patients.

Cbz-N-Amido-dPEG®12-Acid is a PEG compound with two different functional groups (also known as heterobifunctional). Unlike homobifunctional PEG compounds (same functional group on both ends), this type of compounds are more versatile as have two different anchor points. Cbz-N-Amido-dPEG®12-Acid is used as a linker and spacer to add a PEG moiety, via pegylation (a bioconjugation technique) to proteins, peptides, oligonucleotides, small molecules and nanoparticles.

This product contains disulfide bonds between Cys3-Cys14 can is suitable for use in radioimmunoassays. Somatostatin is a peptide hormone that is produced by the hypothalamus and inhibits the release of growth hormones, insulin, and glucagon. It is widely expressed throughout the body for example in the gastrointestinal (GI) tract, hypothalamus, pancreas and the central nervous system. In the central nervous system somatostatin plays a role in neurotransmission modification and it has also demonstrated to be effective against a number of cancers such as squamous carcinoma.

Amino-dPEG® Acid is a PEG compound with two different functional groups (also known as heterobifunctional). Unlike homobifunctional PEG compounds (same functional group on both ends), this type of compounds are more versatile as have two different anchor points. Amino-dPEG® Acid is used as a linker and spacer to add a PEG moiety, via pegylation (a bioconjugation technique) to proteins, peptides, oligonucleotides, small molecules and nanoparticles.

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.

Bis-dPEG®13-Acid is a PEG polymer categorised as homobifunctional PEG (X-PEG X). Used as a linker, bis-dPEG®13-Acid is used to attached PEG to proteins, peptides, oligonucleotides, nanoparticles and small molecules via pegylation, a bioconjugation technique.

Cl-Ac-(OH)Leu-Ala-Gly-NH₂ has been shown to activate PKC by binding to specific domains in the enzyme, which leads to the phosphorylation and activation of PKC's regulatory subunits. This peptide can be used as a research tool in studies involving PKC and also as an antibody carrier for Western blotting and immunohistochemistry.

Ac-Asp-Gln-Thr-Asp-AMC is a synthetic peptide that is used as a research tool for the study of protein interactions and protein function.

Alyerserin-1b is a C-terminally α-amidated 23 residue Cationic anti-microbial peptide (AMP). Anti-microbial peptides (AMPs) are produced by the innate immune system and are expressed when the host is challenged by a pathogen. The Alyerserin family of peptides was first identified in norepinephrine-stimulated skin secretions of the midwife toad-Alytes obstetricans-(Alytidae). Alyteserin-1 peptides have limited structural similarity to the ascaphins from the skins of frogs of the Leiopelmatidae family. Alyteserin-1 peptides are selective at inhibiting growth activity of Gram-negative bacteria-such as Escherichia coli and show weak haemolytic activity against human erythrocytes.Alyteserin contain at least 50% hydrophobic amino acids. Hydrophobic residues contribute to the insertion of the peptide into the hydrophobic membrane core which results in membrane disruption and death of the pathogen. Due to their mechanism of action it is thought to be less likely for resistance to develop towards these peptides compared to conventional antibiotics.

The biological sample was purified by HPLC and the subunits were identified by mass spectrometry. The sequence analysis revealed that Bis-ACV is composed of repeating units that have the structure of N-acetylglucosamine linked via alpha (1->4) glycosidic bonds.
