| Description | Creatine kinase plays a key role in the energy metabolism of cells with intermittently high and fluctuating energy requirements. Examples of such cells include cardiac or skeletal muscle cells and neural tissues of brain and retina. The enzyme catalyzes the reversible transfer of the phosphoryl Creatine kinase plays a key role in the energy metabolism of cells with intermittently high and fluctuating energy requirements. Examples of such cells include cardiac or skeletal muscle cells and neural tissues of brain and retina. The enzyme catalyzes the reversible transfer of the phosphoryl group from phosphorylcreatine to ADP, in order to generate ATP. The molecular mass of the protein is found to be approximately 80 kDa Da. It is made up of 2 subunits, each having a molecular weight of 40 kDa ± 2000. The lighter subunit is present in larger amounts. Applications Creatine phosphokinase from bovine heart has been used to investigate whether endothelial cell growth is stimulated by ischemic hearts. Creatine phosphokinase from bovine heart has also been used to evaluate the effect of high but nontoxic dietary intake of copper and selenium on metabolism in calves. The product has been used for tATPase assay of myofibrillar protein isolated from rabbit. This assay evaluated the kinetic influence of bound creatine kinase (CK) on Ca2+-activated myosin ATPase. The product has also been used for the enzymatic hydrolysis of protein samples during tryptophan estimation by pyrolysis gas chromatography...

It induced intracellular Ca(2+) changes and enzyme release, but no chemotaxis, at concentrations of 100-1,000 nM, and was inactive on T-lymphocytes, neutrophils, and eosinophil leukocytes. Enhances the proliferation of CD34 myeloid progenitor cells. The processed form HCC-1(9-74) is a chemotactic factor that attracts monocytes eosinophils, and T-cells and is a ligand for CCR1, CCR3 and CCR5.Post-translationalThe N-terminal processed forms HCC-1(3-74), HCC-1(4-74) and HCC-1(9-74) are produced in small amounts by proteolytic cleavage after secretion in blood. HCC-1(1-74), but not HCC-1(3-74) and HCC-1(4-74), is partially O-glycosylated; the O-linked glycan consists of one Gal-GalNAc disaccharide, further modified by two N-acetylneuraminic acids...

A35R gene is highly conserved among poxviruses and encodes a previously uncharacterized hydrophobic acidic protein. The A35R has little homology to any protein outside of poxviruses, suggesting a novel virulence mechanism.A35R could block some stage of antigen processing or presentation in infected cells or interfere with regulation of apoptosis. In addition, the A35R function may be required for growth in certain cell types, e.g., macrophage, in vivo. It localizes to factories where viral DNA is located and it was shown to be a constitutive transcriptional activator in a large-scale yeast two-hybrid study...

No other reagents should be added.Working Procedure The following procedure is applicable to nitrocellulose membranes. The procedure must be optimized for other membranes.1.The desired amount of substrate is poured into a sealed container and allowed to reach room temperature, in the dark, before use. 2.After the last incubation with HRP-labelled Streptavidin or HRP-labelled secondary antibody it is recommended to wash the membrane in a 0.1 M Tris buffer pH 7.4.3.Shake off the excess buffer and incubate the membrane in the TMB-D Blotting solution for 10 minutes. 4.Wash the membrane in distilled water and allow it to dry. 5.The site of positive reaction will appear light blue with no or very little background staining.Tips & Tricks • The membrane can be blocked with Kementec’s Synthetic Blocking Buffer for Blotting, (cat. no. S494457). • For long-term preservation of the results, the membranes must be stored in the dark.Handling & Storage • Store solution at 2-8⁰C in the dark. • Avoid exposure to light, heat and contamination with metal ions or peroxidase. • Re-dispense only into bottles made of High-Density Polyethylene (HDPE), amber color.
