We are committed to help unlock the today’s challenge of releasing the energy of glucose that nature has cleverly locked into lignocellulosic biomass. To the untrained eye, starch and cellulose structures appear almost identical. Yet the barriers between cellulosic biomass

Neuropeptidases

We offers many products related to neuropeptidases for your research needs.

Tubulin

Tubulin is the major building block of microtubules. This intracellular cylindrical filamentous structure is present in almost all eukaryotic cells.

Our offers many products related to PKA & PKG for your research needs.

HMG-CoA Reductase (HMGR) Assay Kit

3-hydroxy-3-methylglutaryl-CoA reductase (HMGR) is a transmembrane glycoprotein, located on the endoplasmic reticulum.

Compound Library Screening with LOPAC®1280 Small Molecules

Learn about compound library screening and explore our compound libraries, including our Library of Pharmacologically Active Compounds (LOPAC®1280) portfolio to experience the gold-standard collection of biologically annotated, ready-to-screen compounds.

Phospholipase C

The hydrolysis of a minor membrane phospholipid, phosphatidylinositol 4,5-bisphosphate (PIP2) by a specific phospholipase C (PLC) is one of the earliest key events in the regulation of various cell functions by more than 100 extracellular signaling molecules.

Horseradish Peroxidase (HRP) Enzymes

Discover our peroxidase from horseradish enzymes, products, substrates, and inhibitors for your ELISA, immunoassay, and protein application needs.

G Proteins (Heterotrimeric)

Heterotrimeric G proteins, comprising α, β and γ subunits, respond to extracellular signals generated by activated seven-transmembrane (7TM) receptors by modulating intracellular effector proteins such as enzymes and ion channels.

Enzyme Commission Numbers

Complete List of Enzyme Commission Numbers for metabolics research.

Coenzyme A

Enzyme Reagent Coenzyme A (CoA, CoASH or HSCoA) is the key cofactor in first step of the TCA cycle, responsible for transferring the acetyl group from pyruvate oxidation to oxaloacetate yielding citrate. Available through Sigma-Aldrich online.

Enzymatic Method for Determining Branched Chain Amino Acids (BCAA Assay)

Assay protocol for the colorimetric detection of Branched Chain Amino Acids (BCAA) in biological samples using the alanine assay kit.

Fibrinogen/Fibrin

Fibrinogen is a ~340 kDa glycoprotein synthesised in the liver. It is a hexamer composed of pairs of three peptide chains (α, β, and γ). Fibrinogen is an acute phase protein that is part of the coagulation cascade of

Bioluminescent Firefly Luciferase Assays

Firefly luciferase is a widely used bioluminescent reporter for studying gene regulation and function. It is a very sensitive genetic reporter due to the absence of endogenous luciferase activity in mammalian cells or tissues.

Enzymatic Assay of Cathepsin B

Cathepsin B is a lysosomal cysteine proteinase with broad specificity. This protocol uses Nα–CBZ–Arg–Arg–7–amido–4–methylcoumarin as the substrate for fluorometric detection of Cathepsin B activity.

Nuclear Receptors (PPARs)

Peroxisome proliferator activated receptors (PPARs) are members of the nuclear hormone receptor superfamily of ligand-activated transcription factors that are related to retinoid, steroid and thyroid hormone receptors.

Protein Kinase C (PKC)

Protein kinase C (PKC) is an AGC kinase that phosphorylates serine and threonine residues in many target proteins.

Dipeptidyl Peptidase IV

Native DPPIV is a ubiquitous type II transmembrane glycoprotein and a serine protease of the S9 prolyl-oligopeptidase family. In vivo, it is synthesized with a signal peptide which functions as the membrane anchoring domain.

Cholesterol Esterification

Cholesterol undergoes esterification to improve transport. Cholesterol esters are more easily packaged into the interior of lipoproteins - increasing the quantity that can be readily transported in the blood stream.

Decorin

Decorin is a small proteoglycan, which has been found associated with collagen fibrils in all connective tissues. In the skeletal system it is found primarily in the extracellular matrix of articular cartilage, which covers the surface of adult bones in

Phospholipase D

Phosphatidylcholine (PC)-specific phospholipase D (PLD) enzymes catalyze the hydrolysis of PC to generate choline and phosphatidic acid. These enzymes belong to a superfamily of phosphatidyltransferases with a characteristic unique duplicated catalytic domain motif, the PLD or " HKD"

Drug Conjugate Analysis using β-Glucuronidases

Drug conjugate analysis and the enzymatic hydrolysis of glucuronides

Aprotinin

While aprotinin and bovine pancreatic trypsin inhibitor (BPTI) are the same protein sequence, the term aprotinin is typically used when describing the protein derived from bovine lung.

InsR

We offers many products related to InsR for your research needs.

Enzymatic Method for Determining Amylase Activity (Amylase Activity Assay)

Assay protocol for the colorimetricdetection of amylase activity in biological samples using the Amylase Activity assay kit.

Neurotensin Receptors

Neurotensin is a 13 amino acid regulatory peptide found mainly in gut and brain. Intestinal neurotensin is produced by a discrete population of endocrine cells (N cells) scattered throughout the jejuno-ileal mucosa.
