A multi-user digital laser imaging system for imaging film from bar coded cartridges as a function of image values representative of the images to be printed. The imaging system includes memory for storing transfer functions and film models for each of several users. The transfer functions characterize the relationships between image values and expected imaged film transmittance quantities. The film models characterize the relationship between the transmittance quantities and laser drive values that will provide the appropriate film exposure. An image management subsystem generates lookup tables characterizing the relationship between image values and laser drive values on the basis of user-selected transfer functions and film models selected by the system through the use of film identification information read from the bar code. During imaging operations the image management subsystem accesses the lookup tables as a function of the image values to obtain the appropriate laser drive values. The transfer functions can be modified to accommodate user preferences. Test wedge calibration procedures are periodically implemented to correlate the film models to measured sensitometric characteristics. Density patch calibration procedures are performed during each imaging operation to correct for drifts caused by the film developing subsystem.

The invention discloses a stress phosphorylation antibody aiming at a human Tudor-SN protein T103 site and a preparation method thereof. The preparation method adopts a multifunctional human Tudor-SN protein as a research object and comprises the following steps of determining if threonine at a 103 site of a human Tudor-SN protein under external environment oxidation stress is subjected to phosphorylation modification by near-infrared double-color laser imaging and mass spectrometry, synthesizing a T103 phosphorylation site-containing semiantigen polypeptide according to the secondary structure prediction result, coupling the T103 phosphorylation site-containing semiantigen polypeptide and a carrier protein (KLH) into a complete antigen, carrying out immunization on SPF-level New Zealand white rabbit by the complete antigen combined with an adjuvant four times and collecting, purifying and identifying a T103 specific stress phosphorylation polyclonal antibody. In practical application, Tudor-SN protein epigenetic phosphorylation modification in different stress environments can be detected, the effect mechanism of the Tudor-SN protein epigenetic phosphorylation modification in cell stress tumor propagation and migration can be discussed and a latent action target point for clinical tumor disease diagnosis and treatment is provided.
