Erwinia chrysanthemi (Echr) - DAS ELISA                                         Home    Products    Testing Services   Supplies

Catalog #:  B105
Source Antibody:  Rabbit polyclonal antibodies for both capture and detection.
Test Format:  DAS ELISA                                    

Reactivity:  This ELISA reacted with all Echr isolates tested.  Reaction of the ELISA is very strong.  Optical Density at 405_nm  is in a range of 1.480 - 3.000 depending  on the bacterial titers in the samples tested.

Sensitivity:  Sensitivity of the ELISA is very high.  The bacterium can be consistently detected in infected plant tissues diluted at 1:2430.

Specificity:  This test system reacts negatively with Acidovorax avenae subsp. citrulli, Clavibacter flaccumfaciens, C. michiganensis subsp. insidiosus and C. m. subsp. nebraskensis, C. m. subsp. michiganensis, C. m. subsp. sepedonicus, C. m. subsp. tessellarius, Erwinia carotovora subsp. atroseptica, E. c. subsp. carotovora, E. stewartii, Pseudomonas syringae pv. phaseolicola, P. s. pv. syringae, Ralstonia solanacearum, Xanthomonas campestris pv. armoraciae, X. c. pv. campestris, X. c. pv. citri, X. c. pv. diffenbachiae,  X. c. pv. pelargonii, X. c. pv. phaseoli, and X. c. pv. vesicatoria.  There is no cross reaction with healthy plant tissues.  Background is very low on all of the negative control wells.

Application:  The test can be used to detect Echr in infected host plants as well as in pure bacterial cultures.
