描述

BD-1 Protein, Human is an antimicrobial peptide that defends epithelial surfaces including the skin, gastrointestinal, and respiratory tracts.

研究背景

Recombinant Human Beta Defensin-1 is an antimicrobial peptide that defends epithelial surfaces including the skin, gastrointestinal, and respiratory tracts[1]. Human Beta Defensin-1 may provide a fast-acting antimicrobial coating of tubular lumens in the upper urinary tract to prevent infection by inhibiting bacterial attachment to the urothelium and serving as a second-line chemical shield[2].

生物活性

Full biological activity determined by a chemotaxis bioassay using CD34+ dendritic cells is in a concentration range of 100-1000 ng/mL.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

浓度 (start) × 体积 (start) = 浓度 (final) × 体积 (final)
× = ×
C1   V1   C2   V2

The specific active calculator equation

Specific Active (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Active (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
