| Description | C-Reactive Protein (CRP) is a homopentameric protein with a monomer size of ~24 kDa. It is a member of the pentraxin family, a family of proteins characterized by their calcium dependent ligand binding and unique ring-like structure. Like many other pentraxins, CRP is highly upregulated in the acuteC-Reactive Protein (CRP) is a homopentameric protein with a monomer size of ~24 kDa. It is a member of the pentraxin family, a family of proteins characterized by their calcium dependent ligand binding and unique ring-like structure. Like many other pentraxins, CRP is highly upregulated in the acute-phase response to bodily insults such as tissue injuries, infections and general inflammation. In normal, healthy individuals the concentration of CRP in blood is ~5 mg/ml. This number rises 5-10 fold in response to infection or other causes of inflammation. In severe cases, CRP levels can rise above 200 mg/L. CRP can be used as a biomarker for general inflammation or more specific issues such as certain cancers, diabetes, hypertension, cardiovascular disease (CVD) or Rheumatoid Arthritis (RA). On a cellular/molecular level, CRP activates the complement system of the immune response by binding to surface molecules on dead/dying cells or foreign/invading bacteria. Laboratories and companies investigating the diseases mentioned, complement system induction or the acute phase would find our CRP a useful reagent in their studies. Prepared from plasma shown to be non reactive for HBsAg, anti-HCV, anti-HBc, and negative for anti-HIV 1 & 2 by FDA-required tests. Aladdin products are laboratory reagents and are not to be administered to humans or used for any drug purpose. For research or further manufacturing use only...

It cleavesRibonuclease T1 is an endoribonuclease, highly specific for the cleavage of RNA or deaminated RNA between guanosine 3'-phosphate residues (or inosine 3'-phosphate) and the 5'-OH residues of adjacent nucleotides with the formation of the corresponding intermediate 2', 3'-cyclic phosphates. It cleaves single-stranded RNA releasing oligonucleotides from the guanosine 3'-phosphate termini. The enzyme has a molecular weight of 11 kDa. The optimum pH is 7.5. RNase T1 is inhibited by Ag+, Zn2+, Cu2+, and Hg2+ at 1 X 10-3 M. The stimulatory effects of both histidine and EDTA are attributed to chelation of contaminating inhibitor cations. The enzyme assay is essentially the method of Egami et al., Prog. in Nucleic Acid Res. and Molec. Biol., III, 59 (1964) based upon the release of acid soluble oligonucleotides following the digestion of yeast RNA.Ribonuclease T1 (RNase T1) from Aspergillus oryzae is used to digest denatured RNA prior to sequencing and is used for protein folding studies. ApplicationRibonuclease T1 has extensive applications in molecular cloning and DNA sequencing. Because of its specificity it has been a commonly used cleavage enzyme for the determination of structure, nearest neighbor frequencies, and RNA sequencing. The enzyme has further application in the preparation of nucleoside 2',3'-cyclic phosphates, the synthesis of oligonucleotides, and the removal of RNA from DNA preparations. The enzyme is also used as a non-mammalian source of RNase in various applications... Read More |
