Defensins (alpha & beta) are cationic peptides with a wide spectrum of antimicrobial activity which include a significant arm of the innate immune system. There are 6 human beta-defensins, BD-1, BD-2, BD-3, BD-4, BD-5 and BD-6 which are expressed on some leukocytes and at epithelial surfaces. In addition to their direct antimicrobial activities, beta-defensins can act as chemoattractants towards immature dendritic cells and memory T cells. Beta-defensins contain a 6-cysteine motif which forms 3 intra-molecular disulfide bonds.


BD5 Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 51 amino acids and having a molecular mass of 5.8 kDa. The Beta Defensin-5 is purified by proprietary chromatographic techniques.


Escherichia Coli.

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.


Lyophilized from a 0.2µm filtered concentrated solution in PBS, pH 7.4.


It is recommended to reconstitute the lyophilized Beta Defensin-5 in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.


Lyophilized Beta Defensin-5 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution BD5 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.


Greater than 95.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.

Beta Defensin-5 Human Recombinant: Unleashing the Potential of an Emerging Antimicrobial Peptide




Beta Defensin-5 (hBD-5) human recombinant is an intriguing antimicrobial peptide with diverse properties and promising therapeutic applications. This research paper aims to provide a comprehensive analysis of hBD-5, including its characteristics, mode of action, and potential uses. Furthermore, innovative methodologies for the production and optimization of hBD-5 human recombinant are proposed, offering insights into its future implications in the field of infectious disease management.




The emergence of drug-resistant infections demands innovative solutions to combat pathogens. Antimicrobial peptides, such as hBD-5, have attracted attention due to their broad-spectrum activity. This paper explores the unique features of hBD-5 and presents novel approaches for its production and optimization.


Characteristics and Mode of Action:


hBD-5 is a cationic peptide composed of 41 amino acids and possesses a distinctive structure that contributes to its antimicrobial properties. The mechanism of action involves the disruption of microbial membranes and subsequent destruction of pathogens. Additionally, hBD-5 exhibits immunomodulatory effects by stimulating immune cells and modulating the inflammatory response.


Production of hBD-5 Human Recombinant:


Efficient production methodologies are crucial for the therapeutic application of hBD-5 human recombinant. Various expression systems, including bacterial, yeast, and mammalian cell-based platforms, have been investigated. Each system presents unique advantages and challenges, requiring careful selection to achieve high yields and protein quality.
