Shanghai Jiapeng Frequently Asked Questions for Gel Imaging

Gel imaging is a laboratory instrument for cutting, photographing, observing and analyzing DNA or RNA glue. Gel imaging system can be applied to routine engineering research such as molecular weight calculation, density scanning, density quantification and PCR quantification. Next, gel imaging manufacturers will tell you about the common problems that people often ask when using gel imaging:

The first question: Is the higher the pixel, the better the product?

A: Pixels are for imaging devices. For example, the pixels of a digital camera and a CCD are not comparable. Secondly, the quality of the CCD itself is more important than the pixel level. The most important indicator for the same level of CCD is its size, which is the CCD size. The larger the size, the more its own value grows geometrically.

Second question: What is the main purpose of the accessory UV reflector source?

Answer: The source of UV-reflecting lamps is not widely used. It is mainly used to provide imaging services such as paper chromatography for non-transparent materials. Because the more commonly used transparent agarose gel and polyacrylamide gel, the transmission source can be fully satisfied, so the UV-reflecting light source as an option is not included in the standard.

The third question: Can you cut the gel directly on the gel image?

A: TOCAN gel imaging system can, if you need to directly cut the glue, first press the observation window in the middle of the system to open the observation window with imported anti-UV glass, and then open the small door designed for tapping on the left and right sides. Perform the cutting operation.

Fourth question: How to adjust the focus focus aperture to get a high quality picture?

A: The three most important tunable parameters are focal length, focus, and aperture. Among them, the focal length adjusts the sharpness, the focus adjusts the image size, and the aperture adjusts the brightness and darkness. Generally, the aperture is adjusted to a suitable brightness, then the focus is adjusted to maximize the image, and finally the focal length is adjusted. In the case of a large image, the focal length is relatively easy to adjust to the clearest state, and then the image is scaled to an appropriate size for imaging. Just fine.
