H-Asp(Ala-OH)-OH
CAS:H-Asp(Ala-OH)-OH is an amino acid that has been found to be selectively active in the cerebral cortex. It has a high affinity for the cerebral cortex, with a Kd of 1.5 nM and a brain tissue concentration of 3.3 µg/g. H-Asp(Ala-OH)-OH has been shown to have neuroprotective effects against hypoxia, glutamate toxicity, and oxygen deprivation. This compound reverses the effects of oxidative stress in cultured cells and can also stimulate protein synthesis in cultured cells. The mechanism by which it works is not yet known but may involve inhibition of cysteine uptake into the cell or stimulation of protein synthesis by increasing intracellular levels of cAMP.Formula:C7H12N2O5Purity:Min. 95 Area-%Color and Shape:White PowderMolecular weight:204.18 g/molacfTAT
TAT contains a protein transduction domain which allows it to enter cells by crossing the cell membrane. The amino acid sequence of the protein transduction domain (PTD) and this property confers cell penetrating peptide properties on TAT and derivatives. TAT peptides have been widely used to deliver functional biomolecules into cells both in vitro and in vivo. The entire protein can be used but in practice it is more efficient to use truncated sequences containing only the basic residues required for transport. Through covalent attachment to TAT derived peptides, cargo molecules including proteins, nucleic acids, small molecules, oligonucleotides, enzymes, polymers, plasmid DNA and liposomes can be transported into cells with high efficiency.acfTAT is a fusion of the TAT PTD to a red fluorescent tag (TAMRA) at the carboxy terminal. This peptide is ideal for live cell localisation work using fluorescent microscopy as the TAT PTD can transduce small peptides into the cell efficiently without affecting the cell. Additionally, the fluorescent label is highly stable against photo bleaching and should be easily detectable under various excitation sources including mercury, arc, tungsten, and xenon lamps.Molecular weight:2,095.2 g/molVP1 14-22 (HLA-B*07:02)

CBL-B (22-37) Light
CBL-B (22-37) is derived from the CBL-B E3 ubiquitin ligase which targets receptor tyrosine kinases to lysosome degradation. CBL-B and its family member CBL are expressed in hematopoietic cells and as E3 ubiquitin ligases they contain a tyrosine kinase domain and an RF domain joined by a linker domain. The function of the RF domain is to transfer ubiquitin from E2 ubiquitin-conjugating enzymes onto the target protein which is often phosphorylated. Consequently the ubiquitinated substrate, the receptor tyrosine kinases, are ultimately targeted to the lysosome for degradation.EGFR is an example of a receptor tyrosine kinase whose activation is prevented by CBL and CBL-B when they bind and recruit GRb2, the adapter protein to EGFR. Consequently the ubiquitinylation of EGFR occurs and targets it for recognition by the endosomal protein complex and then lysosome degradation.It has also been found that the CBL family can negatively regulate through ubiquitinylation, PI 3-kinases, Rap G-protein guanine nucleotide exchange factor (GEF), C3G and Rho GTPase GEF Vav which are all non-receptors.If CBL or CBL-B becomes non-functional it can be associated with malignancies such as acute myeloid leukemia and myelodysplastic syndrome.Molecular weight:1,618.9 g/molSubstance P

Cell penetrating peptides (CPPs) provide a delivery method for molecules across the membrane in an efficient manner without compromising the cell. FBP forms a sheet structure when interacting with a membrane forming a transmembranous pore. FBP, also known as Pβ, is rapidly internalised and localises primarily to the nucleus.FBP is provided here with a N-terminal alkyne attachment. Two of the most regularly encountered functional groups for click chemistry are azides and alkynes, and the azide-alkyne cycloaddition has become the most popular click reaction. The use of click chemistry with alkyne-FBP allows a wide variety of applications particularly for conjugation, modification, and peptide design.Color and Shape:PowderMolecular weight:3,013.6 g/molH-K^TSAVLQ-OH

MeOSuc-Ala-Phe-Lys-AMC trifluoroacetate salt
CAS:MeOSuc-Ala-Phe-Lys-AMC is a compound that has a destabilizing effect on the vascular wall, due to its ability to inhibit proteolytic activity. It is also able to reduce the level of angiogenic factors, and thus has an anti-angiogenic effect. MeOSuc-Ala-Phe-Lys-AMC has been shown to have a macroscopic effect on vessels in tissue culture, and this can be observed through leucocyte migration. MeOSuc-Ala-Phe-Lys-AMC has also been shown to cause haemorrhagic changes in microvessels and muscle cells.

Galanin is a widely distributed neuropeptide in the central nervous system, peripheral regions and endocrine system. Galanin has a role in energy homeostasis. Central injections of galanin to the amygdala led to food intake in rats. Galanin also acts in the CNS to inhibit neurotransmitter release, such as acetylcholine. Galanin has been implicated in numerous neurological conditions, including Alzheimer's disease, depression, and epilepsy.Galanin interacts with 3 receptor subtypes, GalR1-3 which are G protein-coupled receptors inserted into the plasma membrane. GalR1 is believed to activate a Gβγ pathway to regulate MAPK activation. GalR2 can also activate the MAPK pathway, but unlike GalR1, there is detectable inositol phosphate production. GalR3 is associated with the Galphai/o pathway. Activation of the receptor leads to a cellular influx of potassium ions.The galanin active fragment (1-16) has been identified as a highly potent agonist for the galanin receptors. These have become a basis for galanin-based peptides, which are neuroactive. These are being investigated as a potential source for anticonvulsant neuropeptides as a therapeutic for conditions such as epilepsy. A library of galanin fragments has allowed screening of their properties to be assessed and used to generate chimeric peptides. Galanin fragments have different affinities for GalR receptors- however, the N-terminal (1-16) have been shown to have a conserved affinity for the receptors.The galanin fragment (2-13) provided here have a C-terminal biotin label for easy detection and purification.

The Histone H2A residues 1 to 20 are derived from histone 2A (H2A) which is one of the four core histones (H2A, H2B, H3 and H4) fundamental in compacting eukaryotic DNA into a structure known as the nucleosome. The nucleosome arises when 147 base pairs of DNA wrap around a H3-H4 tetramer and two H2A-H2B dimers, forming the histone octamer core.At the site of DNA entry on the outer nucleosome, the C-terminus of H2A is present and is able to interact with linker histones or other factors. This allows for variation and changes in nucleosome stability to occur. Furthermore Histone H2A has histone variants such as H2A.Z and H2A.X (which are present in all organisms) and these variants alter the organisation of the DNA.Due to histones containing a large number of lysine and arginine residues they have a positive net charge which interacts in an electrostatic manner with the negatively charged phosphate groups in DNA. The transcriptional activation or silencing of the chromatin is controlled by ATP-dependent chromatin remodelling factors and histone modifying enzymes which target histone proteins. Both processes function to alter to change the positioning of the nucleosome, allowing the DNA it to be either available to the transcription machinery or inaccessible.Biotin has been added to the lysine on GGK.Molecular weight:898.5 g/mol
