    CATALOGUE NUMBER

    CYT-224

    SYNONYMS

    Lymphotoxin-alpha, LT-alpha, TNF-beta, Tumor necrosis factor ligand superfamily member 1, LTA, LT, TNFB, TNFSF1.

    INTRODUCTION

    Lymphotoxin alpha, a member of the tumor necrosis factor family, is a cytokine produced by lymphocytes. LTA is highly inducible, secreted, and exists as homotrimeric molecule. LTA forms heterotrimers with lymphotoxin-beta which anchors lymphotoxin-alpha to the cell surface. LTA mediates a large variety of inflammatory, immunostimulatory, and antiviral responses. LTA is also involved in the formation of secondary lymphoid organs during development and plays a role in apoptosis.

    DESCRIPTION

    Tumor Necrosis Factor-b Human Recombinant (Lymphotoxin) produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 172 amino acids and having a molecular mass of 18645 Dalton.
    The TNF-b is purified by standard chromatographic techniques.

    SOURCE

    Escherichia Coli.

    PHYSICAL APPEARANCE

    Sterile Filtered White lyophilized (freeze-dried) powder.

    FORMULATION

    Lyophilized protein with no additives.

    SOLUBILITY

    It is recommended to reconstitute the lyophilized Tumor Necrosis Factor-beta in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

    STABILITY

    Lyophilized Tumor Necrosis Factor-b although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution TNF-b should be stored at 4°C between 2-7 days and for future use below -18°C.
    For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
    Please prevent freeze-thaw cycles.

    PURITY

    Greater than 98.0% as determined by:
    (a) Analysis by RP-HPLC.
    (b) Analysis by SDS-PAG.

    AMINO ACID SEQUENCE

    MLPGVGLTPS AAQTARQHPK MHLAHSTLKP AAHLIGDPSK QNSLLWRANT DRAFLQDGFS LSNNSLLVPT SGIYFVYSQV VFSGKAYSPK ATSSPLYLAH EVQLFSSQYP FHVPLLSSQK MVYPGLQEPW LHSMYHGAAF QLTQGDQLST HTDGIPHLVL SPSTVFFGAF AL.

    BIOLOGICAL ACTIVITY

    The ED50 as determined by the cytolysis of murine L929 cells in the presence of Actinomycin D is < 0.05ng/ml, corresponding to a Specific Activity of 20,000,000IU/mg.

    PROTEIN CONTENT

    Protein quantitation was carried out by two independent methods:
    1. UV spectroscopy at 280 nm using the absorbency value of 1.082 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).
    2. Analysis by RP-HPLC, using a calibrated solution of TNF-b as a Reference Standard.
