Gel imaging means processing the phototaking and analysising to gel membrane after conducting electrophoresis to the protein,nucleic acid,polypeptide amino acid and other biological molocule in the darkroom or light box through CCD camera.A good gel imaging system mainly contains imaging system,high transmittance lens,high rejection rate specific filter and gel image analysing software system.The quality of the imaging system directly affect user's observing and analysing process to the gel image.
The CCD camera suitable for gel imaging,generally speaking,requires high dynamic range,high full well electric charge,high SNR.Most CCD cameras used for gel imaging nowadays is concentrated between 1.4-5.0MP.As for chemiluminescence users,integral expoure function is required.Since it can't be done to determine the best exposure lenghth of time before the phototaking process is done,and to catch the one time fluorescence signal,we can only adopt the integral exposure,take some line of image sequence and choose the best image to analyse data.Since both of gel imaging and chemilumiescence adopt semiquantitative measuring method,the high dynamic range and full well electric charge will benefit the accuracy of the quantative result and will contribute to bigger inspection range.JPLY S1UC01M camera adopt 2/3'' target surface sony ICX285 research-grade CCD chip.Compared to normal 1/2'' inch chip,this chip has a obviously increased pixel surface to 6.45micron*6.45micron.What's more,the SNR is much better than normal camera,when the amplifer is 1 and exposure time is 20s,JPLY camera can get an average SNR of 88db.Besides,to decrease the working noise of S1UC01M camera and extend exposur time,JPLY adopt advanced 2 level semi-conductor coolling technology which obviously decrease the dark current noise,in this way,the SNR is obviously increased and the exposure time is incrediblely extended.The above advantages make JPLY S1UC01M camera the best choice for gel imaging and chemiluminescence.
