product information
cat :
GPK-100
SKU :
GPK-100_0.5 mg
Product Name :
Lys-Bradykinin
Group Type :
Non Antibodies
Product Type :
Proteins
Applications :
Calcium imaging assay
Formulation :
Lyophilized Powder.
Storage After Reconstitution :
The reconstituted solution can be stored at 4°C for up to 1 week. For longer periods (up to 6 months), small aliquots should be stored at -20°C. We do not recommend storing the product in working solutions for longer than a few days. Avoid multiple freeze-thaw cycles.
Reconstitution and Solubility :
Centrifuge the vial (10,000 × g for 5 minutes) before adding solvent to spin down all the powder to the bottom of the vial. The lyophilized product may be difficult to visualize. Add solvent directly to the centrifuged vial. Gently tap, tilt, and roll the vial to aid dissolution. Avoid vigorous vortexing; light vortexing for up to 3 seconds is acceptable if needed. The product is soluble in pure water at high micromolar concentrations (100 µM - 1 mM). For long-term storage in solution, we recommend preparing a stock solution by dissolving the product in double-distilled water (ddH2O) at a concentration between 100-1000x of the final working concentration. Divide the stock solution into small aliquots and store at -20°C. Before use, thaw the relevant vial(s) and dilute to the desired working concentration in your working buffer. Centrifuge all product preparations before use. It is recommended to prepare fresh solutions in working buffers just before use. Avoid multiple freeze-thaw cycles to maintain biological activity.

Product Page - Scientific background :
Kinins are small peptides rapidly produced following tissue injury that serve as important modulators of inflammation and pain. In the periphery, the actions of kinins include vasodilatation, increased vascular permeability, stimulation of immune cells, and induction of pain. Kinins in the central nervous system (CNS) appear to initiate a similar cascade of events leading to neural tissue damage as well as long lasting disturbances affecting blood-brain barrier function1.Kinins such as Bradykinin (BK), Lys-BK, desArg9-BK, and Lys-desArg9-BK exert their action via two distinct G protein-coupled receptors (GPCR): the B1 Bradykinin receptor (BKRB1) and the B2 Bradykinin receptor (BKRB2)2.Activation of BKRB2 liberates mediators of vascular tone, fibrinolysis, and pain. BKRB2, which mediates most of the physiological effects of kinins, as well as BKRB1, represent potential therapeutic targets for treatment of inflammatory disorders and cardiovascular diseases.Expression of BKRB1 is inducible upon various types of tissue injury and by inflammatory mediators such as bacterial lipopolysaccharide (LPS) and cytokines. A low level of expression of BKRB1 in the CNS of rodent and primates was recently demonstrated3. BKRB2 is constitutively and widely expressed throughout the CNS and peripheral nervous system and on various cell types including endothelial cells, nerve fibers, leukocytes, and mast cells3-5.Lys-Bradykinin is an endogenous nonspecific agonist for BKRB1and BKRB2, with some specificity towards the BKRB26. Activation of Bradykinin receptors with Lys-Bradykinin may induce intracellular Ca2+ elevation7. 100 nM Lys-Bradykinin induced Ca2+ transients in rat aortic endothelium cells (RAEC) (see figure here and review in reference #8).
