Our Abpromise guarantee covers the use of ab9871 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 0.1 - 0.2 µg/ml.

To detect beta 2 Defensin/hBD-2 by Western Blot analysis this antibody can be used at a concentration of 0.1 - 0.2 ug/ml. Used in conjunction with compatible secondary reagents the detection limit for recombinant beta 2 Defensin/hBD-2 is 1.5 - 3.0 ng/lane, under either reducing or non-reducing conditions

Sandwich ELISA Use a concentration of 0.5 - 2 µg/ml.

To detect beta 2 Defensin/hBD-2 by sandwich ELISA (using 100 μl/well antibody solution) a concentration of 0.5 - 2.0 μg/ml of this antibody is required. This antigen affinity purified antibody, in conjunction with ab83509 as a detection antibody, allows the detection of at least 0.2 - 0.4 ng/well of recombinant beta 2 Defensin/hBD-2.

Neutralising Use a concentration of 5 - 8 µg/ml.

To yield one-half maximal inhibition [ND50] of the biological activity of Human beta 2 Defensin/hBD-2 (1.0 μg/ml), a concentration of 5.0 - 8.0 μg/ml of this antibody is required.

The exact immunogen sequence for these antibodies is proprietary so I am sorry we are unable to disclose this information. The immunogen however corresponds to the mature form of Beta 2 defensin protein. We do have sequence listed for ab14426 and ab66072. I wonder if these can help.

Thank you for contacting us.

As discussed we have many anti goat antibodies that can be used in ELISA and ICC/IF.

Idealy enzyme conjugated antibodies e.g. HRP, Alkaline phosphatase are the best suitable antibodies in ELISA. However these will not work in Immunofluorescence unless further steps in protocol applied.

We have FITC, TRITC or Cy5 conjugated antibodies in catalogue that can work in Immunofluorescence and Fluorescence ELISA.

Another option is choosing Biotin conjugated secondary antibody and then buying strepavidin or streptavidin conjugated HRP (ab7403).

ab5753, ab6740, ab6884, ab7124, ab7131 coul dbe a good option.

I know it sounds complicated however this is only way to combine ELISA and ICC/IF with one secondary antibody.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

This antibody is produced using Recombinant Human beta-defensin-2 (BD-2) as the immunizing antigen. BD-2 is an antimicrobial peptide which belongs to the distinct family of beta-defensins. Recent studies have shown that the beta-defensins are present in the human airways and may be relevant to the pathogenesis of cystic fibrosis lung disease. Recombinant Human BD-2 is a 4.3 kDa protein containing 41 amino acid residues. BD-2 sequence GIGDPVTCLK SGAICHPVFC PRRYKQIGTC GLPGTKCCKK P Please see the ELISA protocol linked on the right hand side of the Abcam homepage.
