Biotin

1. Dilute the desired amount of Coating Antibody (COAT) (1 mg/ml) (mouse monoclonal antibody) to 2 ug/ml in PBS without carrier protein and use it fresh.
2. Dilute the desired amount of Detection Antibody (DET) (0.1 mg/ml) (biotinylated mouse monoclonal antibody) to 0.1 ug/ml in ELISA Buffer and use it fresh.
3. Reconstitute the Streptavidin-HRP (STREP) with 100 ul ELISA Buffer. After reconstitution, prepare aliquots and store the reconstituted STREP at -20C. Avoid freeze/thaw cycles. Dilute the reconstituted Streptavidin-HRP to the working concentration by adding 10 ul in 10 ml of ELISA Buffer (1:1000).
4. Reconstitute the Standard Protein (STD) (recombinant human Periostin/OSF-2) with 100 ul ELISA Buffer to obtain a concentration of 1 ug/ml. After reconstitution, prepare aliquots and store the reconstituted standard at -20C. Avoid freeze/ thaw cycles. A standard curve using 2-fold serial dilutions in ELISA Buffer is recommended. Suggested standard points are 5000 pg/ml, 2500 pg/ml, 1250 pg/ml, 625 pg/ml, 312 pg/ml, 156 pg/ml, 78 pg/ml and 0 pg/ml.
