Immunohistochemistry: This antibody stained formalin-fixed, paraffin-embedded sections of human normal pancreas. The recommended concentration is 0.25 ug/mL-0.50 ug/mL with an overnight incubation at 4°C. An HRP-labeled polymer detection system was used with a DAB chromogen. Heat induced antigen retrieval with a pH 6 sodium citrate buffer is recommended. Optimal concentrations and conditions may vary. ELISA: To detect hI-309 by sandwich ELISA (using 100 ul/well antibody solution) a concentration of 0.5-2 ug/ml of this antibody is required. This antigen affinity purified antibody, in conjunction with Biotinylated Anti-Human I-309 (
LS-C104348) as a detection antibody, allows the detection of at least 0.2-0.4 ng/well of recombinant hI-309. Western Blot: To detect human I-309 by Western Blot analysis this antibody can be used at a concentration of 0.1-0.2 ug/ml. When used in conjunction with compatible secondary reagents, the detection limit for recombinant human I-309 is 1.5-3 ng/lane, under either reducing or non-reducing conditions.
