FLAG Epitope Peptide Trifluoroacetate

Supplier: Bachem Americas
Description: The FLAG Epitope Peptide consists of eight amino acids (DYKDDDDK) and represents a versatile fusion tag for the purification of recombinant proteins. It can be enzymatically removed with enterokinase which cleaves C-terminally to the tag sequence. The peptide is commonly used for the elution of immunoaffinity chromatography-purified recombinant proteins.

Fibronectin Adhesion-Promoting Peptide Trifluoroacetate

Supplier: Bachem Americas
Description: The octapeptide Peptide V, WQPPRARI, constitutes one of the heparin-binding amino acid sequences found in the carboxy-terminal heparin-binding domain of fibronectin. The ovalbumin-coupled peptide is able to support cell attachment, and both the ovalbumin-coupled and the free peptides are potent inducers of focal adhesion formation.

E. coli Enterotoxin STp Trifluoroacetate

Supplier: Bachem Americas
Description: Enterotoxigenic E.coli are able to produce several toxic peptides which may cause acute diarrhea in humans and domestic animals. The E.coli heat-stable enterotoxin STp is syntheszied in vivo as a 72 amino acid precursor consisting of pre-, pro-, and mature region. Mature STp is composed of 18 amino acids containing three intramolecular disulfide bonds, which seem to be important for the correct conformation of the biologically active structure.

Vasonatrin Peptide Trifluoroacetate

Catalog Number: (H-2502.0500BA)
Supplier: Bachem Americas
Description: Vasonatrin peptide is a chimera of atrial natriuretic peptide (ANP) and C-type natriuretic peptide (CNP). Its sequence represents the 22 amino acids of CNP plus the 5 C-terminal amino acids of ANP. It possesses the venodilating actions of CNP, the natriuretic actions of ANP, and unique arterial vasodilating actions associated neither with ANP nor with CNP.

Human Peptide YY Trifluoroacetate

Supplier: Bachem Americas
Description: Peptide YY has been isolated from human colonic extracts. It is identical in sequence to porcine PYY except for two amino acid replacements.

Non-Abeta Component of Alzheimer's Disease Amyloid Trifluoroacetate

Supplier: Bachem Americas
Description: The 35 amino acid peptide NAC (α-synuclein (61-95)) has originally been isolated from the insoluble core of Alzheimer's disease (AD) amyloid plaque. The sequence corresponds to a fragment of a 140 amino acid precursor known as NACP or α-synuclein and was found to form amyloid fibrils via a nucleation-dependent polymerization mechanism. Accumulation of NAC aggregates in the synapse might be responsible for the neurodegeneration in AD and in the prion diseases.

Dansyl-Ala-Arg-OH Trifluoroacetate

Supplier: Bachem Americas
Description: Fluorescent substrate for carboxypeptidase M. Because the substrate and the cleavage product Dansyl-Ala-OH are equally fluorescent (λex = 340 nm; λem = 495 nm), the product has to be extracted with chloroform. The uncleaved substrate remains in the aqueous phase (at acidic pH).

Rat Preptin Trifluoroacetate

Supplier: Bachem Americas
Description: Preptin is a 34-amino acid peptide hormone, which is co-secreted with insulin from the pancreatic β-cells in response to glucose stimulation. It is osteogenic in vitro and in vivo and may act in concert with the other β-cell hormones insulin and amylin to stimulate bone formation in hyperinsulinemic states such as obesity.

Rat BNP-32 Trifluoroacetate

Catalog Number: (H-5968.1000BA)
Supplier: Bachem Americas
Description: BNP, originally isolated from porcine brain, belongs to the class of natriuretic peptides, having an amino acid sequence and a pharmacological activity spectrum (including diuretic-natriuretic, hypotensive, and vasorelaxant actions) remarkably similar to that of atrial natriuretic peptide (ANP). Meanwhile, BNP precursor molecules have also been shown to exist in human and rat cardiac tissue. Comparison of the precursor sequences demonstrates structural species differences between the mammalian BNPs, a finding which contrasts with the highly conserved ANP sequences.

Rat Cortistatin-29 Trifluoroacetate

Supplier: Bachem Americas
Description: These synthetic oligopeptides correspond to a region of high amino-acid sequence similarity between uteroglobin and lipocortin I. They possess a potent anti-inflammatory activity in vivo and are strong inhibitors of phospholipase A₂ (PLA₂) in vitro. The name 'antiflammins' is proposed for these peptides, which are a valuable model for the development of novel anti-inflammatory agents of therapeutic importance. See also Cortistatin-29, H-6458, and Thymic Factor, H-4865.

Human Kisspeptin-13 Trifluoroacetate

Supplier: Bachem Americas
Description: An LRF-amide motif containing fragment of malignant melanoma metastasis suppressor KiSS-1. It bound with low nanomolar affinity to the rat and human G protein-coupled receptor GPR54 expressed in Chinese hamster ovary K1 cells and stimulated PIP₂ hydrolysis, Ca²⁺ mobilization, arachidonic acid release, ERK1/2 and p38 MAP kinase phosphorylation, and stress fiber formation but inhibited cell proliferation.

Human Neuromedin S Trifluoroacetate

Supplier: Bachem Americas
Description: The 33-amino acid neuropeptide, neuromedin S (NMS), was originally isolated from rat brain as an endogenous ligand for two orphan G protein-coupled receptors FM-3/GPR66 and FM-4/TGR-1, which have been identified as neuromedin U (NMU) receptors. hNMS-33 is specifically expressed in the suprachiasmatic nuclei (SCN) of the hypothalamus. It has been shown that NMS is implicated in the regulation of circadian rhythms through autocrine and/or paracrine actions.

Cyclo(-Arg-Gly-Asp-D-Phe-Lys) Trifluoroacetate

Supplier: Bachem Americas
Description: An RGD tumor-targeting peptide, which binds to αvβ3 receptors. c(RGDfK) can be easily conjugated to fluorophore tags, chelators, or carriers. Palecek et al. converted the ε-amino group into the azide by diazo transfer allowing further functionalization by click chemistry. Mercapto groups can be introduced via acylation of c(RGDfK) with S-acetylthioacetic acid (SATA).

Biotin-4-fluorescein fluorescent dye, for histology

Catalog Number: (89139-624)
Supplier: Biotium
Description: Biotin-4-fluorescein (N-(5-aminopentyl)biotinamide, trifluoroacetic acid salt) has been reported to be a superior fluorescent biotin derivative for accurate measurement of avidin and streptavidin in crude biological samples. Binding of biotin to avidin and streptavidin is high affinity, fast and noncooperative.
