A measuring point position automatic allocation method for a multi-head measuring apparatus is provided and includes steps as follows: obtaining point position coordinates for all point positions on a surface of a color filter that need measurement, grouping the point position coordinates, matching the Y-axis coordinates of each group with gantry mechanisms corresponding to a measuring range, according to the Y-axis coordinates of the gantry mechanisms matching X-axis coordinates with the measuring head mechanisms, sequentially matching the point position coordinates of all the point positions needing measurement with the gantry mechanisms and the measuring head mechanisms to complete allocation of the point positions.

Multi-head measuring apparatus and measuring point automatic allocation method thereof

An artificial antigen of aflatoxin biosynthetic precursor Sterigmatocystin (ST) and a method for preparing same. Firstly, hydroxyacetic acid is reacted with the double bound of the difuran ring in the aflatoxin biosynthetic precursor ST, yielding an aflatoxin biosynthetic precursor ST hapten with an active carboxymethoxy group. Secondly, a carboxyl group on the ST hapten is attached to an amino group on a carrier protein. At last, the artificial antigen of aflatoxin biosynthetic precursor ST is obtained by dialysis and lyophilize.

A hybridoma cell line ST03 having China Center for Type Culture Collection (CCTCC) accession number C2013187, a monoclonal antibody against aflatoxin biosynthetic precursor ST produced by the hybridoma cell line ST03, and the use of the monoclonal antibody. The hybridoma cell line ST03 can be used for preparing a high-titer monoclonal antibody against aflatoxin biosynthetic precursor ST, and the titer of mouse ascites antibody against aflatoxin biosynthetic precursor ST determined by enzyme linked immunosorbent assay (ELISA) can reach 6.4&#xd7;10. The monoclonal antibody against aflatoxin biosynthetic precursor ST has high sensitivity, has 50% inhibiting concentration ICto aflatoxin biosynthetic precursor ST of 0.36 ng/mL, has no cross reaction with all of aflatoxin B1, aflatoxin B2, aflatoxin G1, and aflatoxin G2, and can be used for the content determination of aflatoxin biosynthetic precursor ST.
