Goat anti Human Defensin beta 2 polyclonal antibody recognizes human Defensin beta-2 (BD-2), a ~4.3kDa cationic antimicrobial peptide, also known as Beta-defensin 4A or Skin-antimicrobial peptide 1 (SAP-1) expressed primarily by epithelial cells of the respiratory tract and skin, and an important component of the innate immune response against microbial infections.

Expression of BD-2 is induced during inflammation in response to bacterial products and cytokines, and is initially expressed in a precursor form, which is cleaved to release the C-Terminal active portion of the protein which is secreted by the neutrophil and binds to bacterial membranes causing their disruption.

Target Species
Product Form
Purified IgG - lyophilized
Reconstitute with 1.0ml distilled water
Care should be taken during reconstitution as the protein may appear as a film at the bottom of the vial. Bio-Rad recommend that the vial is gently mixed after reconstitution. For long term storage the addition of 0.09% sodium azide is recommended.
N.B. For functional studies do not add sodium azide
Antisera to human Defensin beta 2 were raised by repeated immunisation of goats with highly purified antigen. Purified IgG was prepared by affinity chromatography.
Buffer Solution
Phosphate buffered saline
Preservative Stabilisers
None present
Carrier Free
Recombinant human Defensin beta-2 (PHP161).
Approx. Protein Concentrations

12 months from date of despatch

Prior to reconstitution store at -20°C.
After reconstitution store at -20°C.

This product should be stored undiluted. Storage in frost-free freezers is not recommended. Avoid repeated freezing and thawing as this may denature the antibody. Should this product contain a precipitate we recommend microcentrifugation before use.

Where this antibody has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. Suggested working dilutions are given as a guide only. It is recommended that the user titrates the antibody for use in their own system using appropriate negative/positive controls.
This purified human BD-2 antibody may be used in an indirect ELISA or as the capture reagent in a sandwich ELISA with a biotinylated human BD-2 antibody (AHP849B) as the detection reagent and recombinant human BD-2 (PHP161) as the standard
Western Blotting
This purified human BD-2 antibody may be used in Western Blotting applications under either reducing or non-reducing conditions with recombinant human BD-2 (PHP161) as the positive control.
