    CATALOGUE NUMBER

    ENZ-656

    SYNONYMS

    DNA topoisomerase 1, EC 5.99.1.2, DNA topoisomerase I, TOP1, Scl-70.

    INTRODUCTION

    TOP1 is an important nuclear enzyme that interconverts supercoiled DNA to the necessary topological conformations for standard DNA replication and transcription. TOP1 is the target antigen for TOP1 autoantibodies. TOP1 antibodies are a specific marker in scleroderma patients (specificity 98-100%) and are related with the existence of diffuse skin involvement and pulmonary fibrosis. In human tissues top1 enzyme is primarily synthesized as a protein with a molecular weight of 100-kDa. Most of this precursor is then proteolytically processed to a 70-kDa size, from which the TOP1 antigen has derived its name.

    DESCRIPTION

    Bovine DNA Topoisomerase-I shows multiple bands between 76-109 KDa and is purified from bovine tissues by proprietary chromatographic techniques.

    SOURCE

    Bovine tissues.

    FORMULATION

    TOP1 is supplied in 20mM HEPES buffer pH-7.5, 400mM NaCl and 20% glycerol.

    IMMUNOLOGICAL FUNCTIONS

    1. Binds IgG-type human auto-antibodies.
    2. Standard ELISA test (checkerboard analysis of positive/negative samples) and immunodot test with positive/negative samples.

    APPLICATIONS

    Western blot with anti TOP1 autoantibody positive sample.

    COATING CONCENTRATION

    0.5-0.8 µg/ml (depending on the type of ELISA plate and coating buffer). Suitable for labeling of functional groups.

    PURITY

    Greater than 95% as determined by SDS-PAGE.

    STABILITY

    Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. 
    Avoid multiple freeze-thaw cycles.

    SAFETY DATA SHEET

    SDS

    USAGE

    Prospec's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.

    • DNA Topoisomerase II-Catalyzed DNA Decatenation

      A major role of DNA topoisomerase II in vivo is to catalyze the double-stranded cleavage of DNA, allowing passage of a second DNA duplex through the break. This activity requires adenosine triphosphate (ATP) and is necessary for separating

    • Purification of DNA Topoisomerase I from Human Placenta

      DNA topoisomerase I (topo I) has been firmly established as the molecular target of the camptothecin group of anticancer drugs. These drugs include camptothecin, topotecan, 9-amino-camptothecin, and irinotecan

    • Assaying DNA Topoisomerase I Relaxation Activity

      Type I topoisomerases catalyze topological changes in duplex DNA by reversibly nicking one strand, whereas type II enzymes catalyze the transient breakage of both strands simultaneously. The type I enzymes alter the linking number
