1. The main core components of Drop-seq are pressurization device and droplet microfluidic synthesis device. The principle uses pressure to press three materials, namely magnetic beads, cells and mineral oil, into the microchannel to achieve three thingsThe mass was mixed into a large droplet to complete the single cell separation mark, and the library was continued after completion.
2, in fact, we know that microfluidic can not only be combined with NGS, microfluidic mass spectrometry can do single-cell metabolism, microfluidic electroseepage can do cell sorting, microfluidic optics can do single-cell fluorescence imaging and so on.
3. Use flow cytometry. If the target protein itself is a fluorescent protein, it can be screened directly. Otherwise, use fluorescently labeled antibodies to stain and screen later. 3. With a magnetic cell sorter.
4. Early single-cell capture methods include micropipetting and micromanipulationAnd laser capture microdissection [26-27]. Compared to several methods commonly used today, these methods have low throughput, are technically challenging, and require time and effort, but can still be used when the number of cells to be analyzed is small, such as rare cells.
5, Fluidigm C1 platform, is the first commercial sorting technology applied in the field of Single Cell, based on Fluidigm microfluidic technology, about 96 cells can be captured in a few hours for all kinds of single-cell sequencing library. Of courseThe flux is still relatively small.
6. Cell lysis, reverse transcription and cDNA amplification were performed in the microfluidic chip, followed by sequencing. The representative method is Fluidigm C1 sequencing platform, which has high precision and high cost.
1, finally check the LED chip (VC) and label. The chip area should be in the center of the blue filmThere are a maximum of 5000 chips on the blue film, but it must be ensured that the number of chips on each blue film is not less than 1000, and the chip type, batch number, quantity and photoelectric measurement statistics are recorded on the label, attached to the back of the wax paper. 2, in general, the LED production process is divided into two parts: First, the production of gallium nitride (GaN) based epitaxial sheet on the substrate, this process is mainly completed in the metal-organic chemical vapor deposition epitaxial sheet furnace (MOCVD).
3, install the power supply: check whether the aluminum substrate is stuck crooked, stick tight, put the power supply from the aluminum substrate there is "LED.The "LED-" side is loaded into the aluminum tube, the white wire end is loaded first, the longer white wire is threaded to the other side of the aluminum tube, and the power supply is put into the aluminum tube. 4, LED chip sorting is very difficult, the main reason is that the LED chip size is generally very small, from 9mil to 14mil (0.22-0.35 microns).
5, LED chip inspection microscopy: whether there is mechanical damage and pitting pits on the surface of the material (lockhill chip size and electrode size meet the process requirements whether the electrode pattern is complete LED expansion due to the LED chip after the bladeHowever, the tight spacing is very small (about 0.1mm), which is not conducive to the operation of the post-process.
1, LED chips are composed of arsenic, aluminum, gallium, indium, phosphorus and nitrogen, and are divided into general brightness, high brightness, ultra-high brightness, and even infrared and photoelectric components according to the brightness and composition of the elements. From binary to four-element wafers, each category has its own unique performance and application areas.
2, LED chip classification: according to the composition can be divided into: binary, ternary, four LED chip. The so-called binary, ternary, four-element LED chip refers to the number of effective elements contained in the chip.
3, according to the shape classification, the chip is generally divided into round and square pieces. Among them, the wafer is relatively low grade, the performance is not stable enough, generally do not use the led produced by the wafer; Squares are generally measured in size, such as 12 mil (1 mil =0.0254 square mm).
4, Abstract: LED display driver chip types? LED driver chips can be divided into general chip and special chip two. The so-called universal chip,The chip itself is not specifically designed for leds, but some logic chips with some logic functions of the LED display (such as series-and-shift registers).
5, LED chips are mainly sapphire substrate, silicon substrate and silicon carbide substrate three kinds of sapphire substrate: the market share ranks first, is from the Japanese company's patented technology.
6, there are a lot of direct insertion. The basic models are F3, F5, etc. This thing is currently mainly to do indicator light, lamp string class. High power, the current high power is said to be more than 0.5W (including 0.5W) LED. This is also a photo.The mainstream of the Ming market, many days of lanterns, spotlights, downlights, and so on are used in this thing.
