Prolactin Protein, Rat (His)

Customer Review

Based on 1 Customer Validation

Prolactin Protein primarily promotes lactation by exerting its main actions on the mammary gland.This crucial function is facilitated through interaction with its specific receptor, PRLR.Prolactin Protein, Rat (His) is the recombinant rat-derived Prolactin protein, expressed by E.coli , with N-6*His labeled tag.

Biological Activity

Description

Prolactin Protein primarily promotes lactation by exerting its main actions on the mammary gland.This crucial function is facilitated through interaction with its specific receptor, PRLR.Prolactin Protein, Rat (His) is the recombinant rat-derived Prolactin protein, expressed by E.coli , with N-6*His labeled tag.

Background

Prolactin protein exerts its main actions on the mammary gland, primarily promoting lactation. This crucial function is achieved through its interaction with the specific receptor known as PRLR, which facilitates the process of lactation.

Product Properties

Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.22 μm filtered solution of 50 mM Tris-HCl, 300 mM NaCl, 200 mM arginine, pH 8.0.
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
