Biological Activity

Description

Prolactin Protein acts on the mammary gland, promoting lactation through its interaction with the receptor PRLR. Prolactin Protein, Human (sf9, His) is the recombinant human-derived Prolactin protein, expressed by Sf9 insect cells , with C-10*His labeled tag.

Background

Prolactin is a protein that primarily acts on the mammary gland by promoting lactation. It achieves this by interacting with its receptor, PRLR.

Verified Bioactivity

1.Measured by its ability to promote proliferation of INS-1 cells and the ED50 is typically 5.6 ng/mL.
2.Measured in a cell proliferation assay using Nb2-11 rat lymphoma cells. The ED50 for this effect is 0.6-1.0 ng/mL.

Product Properties

Appearance

Lyophilized powder.

Formulation

1.Lyophilized from a 0.22 μm filtered solution of 20 mM Tris-HCl, 500 mM NaCl, pH 8.0, 20% glycerol.
2.Lyophilized from a 0.22 μm filtered solution of 20 mM Tris-HCl, 500 mM NaCl, pH 8.0, 10% glycerol.
Please refer to the lot-specific COA for specific buffer information.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping
