Unrivaled 
| 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
- Human
- Product Form
- Purified IgG conjugated to Biotin - lyophilized
- Reconstitution
- Reconstitute with 0.5 ml sterile PBS containing 0.1% bovine serum albumin
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. - Preparation
- 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
- Yes
- Immunogen
- Recombinant human Defensin beta-2 (PHP161).
- Approx. Protein Concentrations
- IgG concentration 0.1 mg/ml after reconstitution
- Regulatory
- For research purposes only
- Guarantee
- 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.
- ELISA
- This biotinylated human DB-2 antibody may be used in a direct ELISA or as the detection reagent in a sandwich ELISA with a purified human BD-2 antibody (AHP849) as the capture reagent and recombinant human BD-2 (PHP161) as the standard.
- Western Blotting
- This biotinylated 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.
