A modified tripeptide reversible protease inhibitor of trypsin-like proteases and some cysteine proteases including endoproteinase Lys-C, kallikrein, papain, thrombin, cathepsin B, cathepsins H and L, trypsin, calpain, trypsin and plasmin. Little to no inhibition is seen against pepsin, cathepsins A and D and alpha-chymotrypsin. When adjusted for molarity, all three salt forms are equally effective; however, the hydrochloride salt is usually less invasive in biological settings. Leupeptin, because of its aldehyde group, may act as a reducing agent and therefore interfere in protein determinations such as Lowry and, to a lesser extent, Bradford.

C-peptide is cleaved from proinsulin, stored in secretory granules, and eventually released into the bloodstream in amounts equimolar with those of insulin. The measurement of the C-peptide is an important test for the beta-cell function. In the red blood cells of type 2 diabetic patients, Na+,K+ ATPase activity is strongly related to blood C-peptide levels. C-peptide signal transduction in human renal tubular cells involves the activation of phospholipase C and PKC-delta and PKC-varepsilon, as well as RhoA, followed by phosphorylation of ERK1/2 and JNK and a parallel activation of Akt. C-peptide shows specific binding to a G-protein-coupled membrane binding site, resulting in Ca2+ influx, activation of mitogen-activated protein kinase signalling pathways and stimulation of Na+, K+ ATPase and endothelial nitric oxide synthase.

This chimeric peptide is a fragment derived from rabies virus glycoprotein (RVG). Because neurotropic viruses cross the blood-brain barrier to infect brain cells, the same strategy may be used to enter the central nervous system and deliver siRNA to the brain. To enable siRNA binding, this chimeric peptide was synthesized by adding nonamer arginine residues at the carboxy terminus of RVG. This RVG-9R peptide was able to bind and transduce siRNA to neuronal cells in vitro, resulting in efficient gene silencing. After intravenous injection into mice, RVG-9R delivered siRNA to the neuronal cells, resulting in specific gene silencing within the brain. RVG-9R provides a safe and noninvasive approach for the delivery of siRNA and potentially other therapeutic molecules across the blood–brain barrier.

Ciprofloxacin is a fluorinated quinolone antibacterial agent which is highly effective against a broad spectrum of bacteria and mycoplasma.
Ciprofloxacin is most commonly used to treat infections of the skin, bone, sinus, lung, abdomen, and bladder. It can also be used to treat some sexually transmitted infections. Additionally, ciprofloxacin can be used after exposure to inhalation anthrax to reduce the chance of developing an infection.
During the proliferation phase of a bacterium a segmental twisting and untwisting of the chromosomes take place. An enzyme called DNA gyrase plays a decisive part in this process. Ciprofloxacin inhibits this DNA gyrase in a way that arrests the bacterial metabolism, since vital information can no longer be read from the bacterial chromosome. Ultimately, it affect DNA replication & cell division.
Store at +4 °C.

Big Gastrin is also referred to as Gastrin-34. Secretion of gastrin is induced by food intake and causes the release of gastric acid in the stomach. Secreted by the G cells in the gastric mucosa, it is one of the major bioactive forms of gastrin found in tissue and plasma (the other bioactive form is gastrin-17 or little gastrin - Cat# AS-20750). Both gastrin-17 and gastrin-34 are carboxy-amidated and partially tyrosine sulfated. Binding of gastrin to the CCK2/gastrin receptor requires carboxy-amidation, however sulfation is not necessary for binding to the receptor. Binding of Gastrin to the CCK2/gastrin receptors on parietal cells of the stomach causes them to secrete hydrochloric acid (HCl) and stimulates lectin-like protein Reg expression via activation of PKC and RhoA. Gastrin also plays a role in release of Histamine and Pepsinogen.

Matrix Metalloproteinases (MMPs) are a large family of endopeptidases. Collectively, MMPs can degrade all kinds of extracellular matrix proteins, and can also process a number of bioactive molecules. They are known to be involved in the cleavage of cell surface receptors, the release of apoptotic ligands, and chemokine/cytokine inactivation. MMPs are also thought to play a major role in cell behaviors such as cell proliferation, migration (adhesion/dispersion), differentiation, angiogenesis, apoptosis, and host defense.

NFF-3 is hydrolyzed rapidly by MMP-3 (kcat/Km = 218,000 s-1 M-1) and very slowly by MMP-9 (kcat/Km = 10,100 s-1 M-1), but no significant hydrolysis by MMP-1 and MMP-2. It is one of the few synthetic substrates selectively hydrolyzed by certain members of the MMP family and thus has important applications for the differentiation of MMP-3 activity from that of other MMPs. Abs/Em = 325/393 nm.

AASTYs (Acrylic acid-co-styrenes) - like AASTY 11-50 - are highly-alternating copolymers, well-suited for the generation of native lipid nanodiscs. They are a 2022 novel developed series for membrane protein solubilization & stabilization. AASTY 11-50 gets its name from its molecular weight and Acrylic Acid : Styrene Ratio. These varying ratios of acrylic acid to styrene contribute to the hydrophilic properties of our AASTYs. In general lighter AASTYs, like 6-45 tend to be more aggressive, while heavier AASTYs, such as 11-50 show higher thermodynamic stability.

Every membrane protein solubilization needs to undergo a screening process in before. The characteristic phospholipid environment surrounding the different membrane proteins in question performs differently well with each polymer. To support you in this process, we offer a handy Screening Kit for AASTYs to test them all.

We recommend the two following publications if you would like to get further information: Smith et al. 2020 & Timcenko et al. 2022
