Biological Activity

Description

BD-3 Protein, Rat is an inducible antimicrobial peptide and exhibits broad-spectrum antimicrobial activity.

Background

Recombinant Rat Beta Defensin-3 is an inducible antimicrobial peptide and exhibits broad-spectrum antimicrobial activity. Beta Defensin-3 peptide exhibits broad-spectrum antimicrobial activity, this peptide may serve as an innate defense against microbial invasion at specific mucosal surfaces[1].

Verified Bioactivity

The ED50 is 4-20 μg/mL as measured by its antimicrobial activity against E. coli.

Product Properties

Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.

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.
