产品描述

Prolactin Ovine Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 199 amino acids and having a molecular mass of 23 kDa. The Prolactin n is purified by proprietary chromatographic techniques.

Product Data

Purity Greater than 99.0% as determined by:(a)Gel filtration analysis.(b) Analysis by SDS-PAGE. Source Escherichia Coli.
Phycical Appearance Sterile Filtered White lyophilized (freeze-dried) powder. Shipping Condition Shipped at Room temp.
Synonyms Mammotropin; Luteotropic hormone; Luteotropin; PRL.
Amino Acid Sequence The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Thr-Pro-Val-Cys-Pro.
Solubility It is recommended to reconstitute the lyophilized Prolactin in sterile 18MΩ-cm H2O or 0.4% NaHCO3 adjusted to pH 8-9, 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.
Biological Activity Is fully biologically active as evidenced by inducing proliferation of Nb2 cells.
Formulation The protein was lyophilized from a concentrated (1mg/ml) solution with 0.02-0.03% NaHCO3.

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.

Biological Activity

Is fully biologically active as evidenced by inducing proliferation of Nb2 cells.

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.
