Activity
Determined by its ability to chemoattract immature dendritic cells using a concentration of 10.0-100.0 ng/ml.
Target Species
Human
Applications Tested/Suitable for DEFB4B active protein
ELISA (EIA), Functional Assays (FN), Western Blot (WB)
Application Notes for DEFB4B active protein
ELISA: Recombinant human BD-2 may be used as a standard in ELISA applications with either a purified human BD-2 antibody or a biotinylated human BD-2 antibody.
Western Blot: Recombinant human BD-2 may be used as the positive control in Western Blotting applications with either a purified human BD-2 antibody or a biotinylated human BD-2 antibody.
ELISA: Minimum Dilution: 0.2; Maximum Dilution: 0.4ng/well
Functional Assays: Minimum Dilution: 10; Maximum Dilution: 100ng/ml
Western Blotting: Minimum Dilution: 1.5; Maximum Dilution: 3.0ng/lane

Other Notes

Small volumes of DEFB4B active protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
