Purity:  99.91%
Synonyms: Exenatide acetate
Exendin-4 acetate (Exenatide acetate) is an orally active, blood-brain barrier-permeable glucagon-like peptide-1 receptor (GLP‑1 receptor) agonist that resists degradation mediated by dipeptidyl peptidase IV. Exendin-4 acetate mediates multiple glucose-regulating effects, including stimulation of glucose-dependent insulin secretion, inhibition of glucagon production, increase in β-cell mass, delay of gastric emptying, reduction of food intake, improvement of peripheral insulin sensitivity, and restoration of normal islet structure. Exendin-4 acetate inhibits oxidative stress, alleviates inflammatory responses, and reduces neuronal apoptosis. Exendin-4 acetate reduces the aggregation level of mutant huntingtin, improves motor function, prolongs survival time, and regulates the expression levels of leptin and ghrelin. Exendin-4 acetate can be used in research related to type 2 diabetes, acute ischemic stroke, and Huntington's disease .

Infection

Gramicidin S (Gramicidin soviet) is a cationic cyclic peptide antibiotic that selectively targets bacterial cell membranes and has anticancer activity. Gramicidin S also exerts antibacterial activity by destroying membrane integrity and interfering with membrane protein function. Gramicidin S inserts into the phospholipid bilayer through hydrophobic amino acid residues, specifically binds to negatively charged membrane lipids and disrupts membrane structure, thereby inhibiting cell division and cell wall synthesis, and ultimately causing bacterial death. Gramicidin S also inhibits ion channels, with IC50s of 41 μM, 24 μM, and 3 μM for Na +/K +-ATPase, tobacco leaf plasma membrane Mg 2+/K +-ATPase, and rat heart plasma membrane Ca 2+-ATPase, respectively .

Synonyms: LPS, from bacterial (Klebsiella pneumoniae)
Lipopolysaccharides, from Klebsiella pneumoniae (LPS, from bacterial (Klebsiella pneumoniae)) are lipopolysaccharide endotoxins and TLR4 activators derived from Klebsiella pneumoniae, and are classified as S-type LPS. Lipopolysaccharides, from Klebsiella pneumoniae exhibit a typical three-part structure: O-antigen, core oligosaccharide, and lipid A. Lipopolysaccharides, from Klebsiella pneumoniae may participate in bacterial immune evasion by inhibiting complement-mediated killing and suppressing the host's secretion of antimicrobial peptides, thereby allowing the bacteria to escape immune defenses. Lipopolysaccharides, from Klebsiella pneumoniae possess high viscosity and resistance to serum-mediated killing, which may lead to sepsis. Lipopolysaccharides, from Klebsiella pneumoniae can be used to construct Acute Lung Injury Model .
It is recommended to prepare a solution with concentration ≥2 mg/mL. Vortex thoroughly for more than 10 minutes. Due to the adsorption characteristics of LPS, silanized container or low adsorption centrifuge tubes should be used for aliquoting and storage, and mix thoroughly before use.

2-Aminoethyl-mono-amide-DOTA-tris(tBu ester) is a metal chelator precursor containing a DOTA macrocyclic structure. DOTA can form highly stable complexes with metal ions (such as 68Ga, 177Lu) through four nitrogen atoms and four carboxylic acid groups to mediate targeted delivery of radionuclides. The tert-butyl ester group (tBu ester) of 2-Aminoethyl-mono-amide-DOTA-tris(tBu ester) also protects the carboxylic acid group during synthesis, and forms a free carboxyl group after deprotection reaction for coupling with targeting molecules (such as antibodies, peptides). 2-Aminoethyl-mono-amide-DOTA-tris(tBu ester) may be combined with tumor pre-targeting systems through bioorthogonal reactions (such as reverse electron demand Diels-Alder reaction) to study radioactive imaging or therapy of tumor tissues, and is mainly used in tumor pre-targeting research in the field of nuclear medicine .

D-Phenylalanine is an atypical D-amino acid and an inhibitor of bacterial biofilm formation. D-Phenylalanine mainly replaces D-alanine (D-Ala) by incorporating into the fourth and fifth positions of bacterial peptidoglycan (PG), changing the cell wall structure, enhancing bacterial acid resistance and affecting biofilm formation. D-Phenylalanine may promote the secretion of peptide tyrosine tyrosine (PYY) in mammals by activating the intestinal GPR109B receptor. D-Phenylalanine can inhibit the maturation of microbial biofilms and promote the release of specific hormones. It can be used for antibacterial preservation, improving the yield of probiotics in the food industry, and studying appetite regulation and blood sugar control in metabolic diseases such as diabetes .

L17E is an attenuated cationic amphiphilic lytic (ACAL) peptide that can be used to deliver a variety of macromolecules, including proteins, antibodies, and DNA nanostructures. L17E inserts and cleaves the membrane structure through electrostatic interaction, enabling intracellular escape. The efficiency of L17E-mediated delivery is strongly correlated with the expression level of KCNN4 (the gene encoding the calcium-activated potassium channel KCa3.1). L17E also promotes the cellular uptake of macromolecules by inducing micropinocytosis. L17E can be further optimized and improved through dimerization strategies and in combination with other delivery systems, such as nuclear localization signal peptides and cell membrane-coated nanoparticles .
