The gross weight of laser pointer should be greater

 The gross weight of laser pointer should be greater than net weight of laser pointer .
At present, a complete configuration LSCM has been completely able to functionally replace any previous an optical microscope, which is equivalent to a variety of well-made organic combination of commonly used optical microscopy, such as the inverted optical microscope, ultraviolet microscopy, fluorescence microscopy, the dark field microscopy, phase contrast microscopy (PH), differential interference contrast microscopy (DIC), etc., it is called the universal microscope, it has been fine image by other microscope can image very inferior. Observation of living cells, living tissue without damaging the cell LSCM under the premise of living tissue, living cells were observed and measured, not only eliminating the tedious sample pre-treatment process (such as dehydration, wax, dye, etc.); and observation can continue over the sample for other studies. The shipping fee of laser pointer should be calculated according to the gross weight of laser pointer .
This function for cell culture, transgenic research is particularly important. It can be said that the biggest advantage of LSCM. Biochemical composition of precise positioning observed with specific molecular probes for the detection of the ingredients to not only locate the cellular level, you can also navigate to the sub-cellular level and molecular level dynamics observed at the same time the sample plane with continuous scanning, you can analysis of cell structure, containing, and marking dynamics. Currently done in this regard is the use of LSCM observation of most cardiac or smooth muscle intracellular free calcium, sodium, potassium ion concentration or pH dynamics. Data, digital images using a computer instead of an ordinary camera, the resulting image is digitized, it may output or long-term storage, but also for further processing. The gross weight of laser pointer is 500g.
The first application of quantitative measurement of fluorescent probes specific staining of samples, sample composition and the measured fluorescence intensity was proportional to the content, if other conditions are fixed, between the sample groups by comparing the fluorescence intensity, can be drawn from a specific component content ratio. Single experimental specimen requirements, and can well attached to the sample pool. Therefore, a tissue either frozen section or paraffin section, are the thinner the better. Commonly attached to the agent are: poly-lysine, concanavalin A, egg white, gelatin agar cell-Tak, vectabond and so on. Cultured cells to meet the requirements, if the purchase of the instrument brought Bodi flasks for culture is better. The gross weight of laser pointer is composed of the net weight and package weight.
