    CATALOGUE NUMBER

    CYT-513

    SYNONYMS

    Mammotropin, Luteotropic hormone, Luteotropin, PRL.

    INTRODUCTION

    Prolactin is a neuroendocrine hormone synthesized primarily by the pituitary gland but also a variety of other cell types including the placenta, brain and uterus. Its primary function is to promote and maintain lactation but has also been shown to have a role in breast cancer development, regulation of reproductive function and immunoregulation.

    DESCRIPTION

    Prolactin Rabbit Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 200 amino acids and having a molecular mass of 23007 Dalton.
    The Porlactin is purified by proprietary chromatographic techniques.

    SOURCE

    Escherichia Coli.

    PHYSICAL APPEARANCE

    Sterile Filtered White lyophilized (freeze-dried) powder.

    FORMULATION

    The protein was lyophilized from a concentrated (1mg/ml) solution with 0.0045mM NaHCO3.

    SOLUBILITY

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

    STABILITY

    Lyophilized Prolactin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Prl 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 SEC-HPLC.
    (b) Analysis by SDS-PAGE.

    AMINO ACID SEQUENCE

    The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Leu-Pro-Ile-Cys.

    BIOLOGICAL ACTIVITY

    The ED50 as determined by the dose-dependant stimulation of the proliferation of rat lymphoma, Nb2-11 was found to be < 0.065ng/ml.

    PROTEIN CONTENT

    Protein quantitation was carried out by two independent methods
    1. UV spectroscopy at 280 nm using the absorbency value of 0.87 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 Prolactinl as a Reference Standard.

    SAFETY DATA SHEET

    SDS
