Fetuin B Protein, Mouse (HEK293, His)

Customer Review

Based on 1 Customer Validation

Fetub Protein, a glycoprotein, plays a significant role in regulating insulin sensitivity and lipid metabolism. Dysregulation of Fetub Protein has been associated with several diseases, including obesity and type 2 diabetes. Fetuin B Protein, Mouse (HEK293, His) is the recombinant mouse-derived Fetuin B protein, expressed by HEK293 , with C-His labeled tag.

Biological Activity

Description

Fetub Protein, a glycoprotein, plays a significant role in regulating insulin sensitivity and lipid metabolism. Dysregulation of Fetub Protein has been associated with several diseases, including obesity and type 2 diabetes. Fetuin B Protein, Mouse (HEK293, His) is the recombinant mouse-derived Fetuin B protein, expressed by HEK293 , with C-His labeled tag.

Background

Fetub protein is an essential protease inhibitor involved in the process of egg fertilization. Its primary role is to prevent the premature hardening of the zona pellucida before fertilization can take place. This is likely achieved through the inhibition of ASTL, a protease responsible for cleaving ZP2 and initiating the hardening of the zona pellucida.

Product Properties

Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.22 μm filtered solution of 20 mM Tris, 150 mM NaCl, pH 7.5.
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

Room temperature in continental US; may vary elsewhere.
