If the liquid flow rate is slow, the rotation speed can be appropriately increased.12.Add 200µL of Wash buffer II (shake for 10-20s before use) to the desalting column, centrifuge at 2500rpm for 3-5min until all the liquid is centrifuged down.13.Add 200µL of Wash buffer III to the desalting column, centrifuge at 2500rpm for 3-5min until all the liquid is centrifuged down.14.Put the desalting column into a new EP tube, add 200µL of Elution buffer to the desalting column, centrifuge at 2000rpm for 3-5min until all the liquid is centrifuged down.15.Repeat the previous step, collect the eluates from both times, and freeze-dry them.16.Add 10µL of Loading buffer, vortex vigorously for 3min, centrifuge at 2000g for 10min, take an appropriate amount of sample for mass spectrometry detection. Taking the HF-X instrument as an example, 0.5-1µg of sample is sufficient for loading. Automated Operation Process:It is compatible with mass spectrometry proteomics pretreatment workstations, enabling one-stop processing from plasma to peptides. This eliminates manual operation errors, improves the reproducibility of sample preparation workflows, and provides high precision and reliability for various laboratory procedures...

This is achieved by (1) spiking a complex Internal Standard (WORKFLOW-A) into a biological sample to a) quantify all the biochemicals in the sample relative to their counterparts in the Internal Standard, b) suppression-correct each compound and c) normalize sample to sample variances; and (2) injecting the same well characterized Long-Term Reference Standard (WORKFLOW-B) to create a daily retention time (RT) library of all compounds to be found in the Internal Standard for reproducible ID, and to measure day-to-day (QA/QC) to assure reproducible instrument performance. The system is completely automated using IROA ClusterFinder™software.IROA TruQuant IQQ Workflow Kit contains the materials and tools for the analysis of 90 experimental samples. The kit is intended to be used for mass spectrometry metabolomics applications...

The total time for single-cell amplification is about 3 hours, and 2-5 µg of genomic DNA, with a size of 200-1500 bp, can be obtained after lysis, pre-amplification and amplification. The amplified product can be widely used in second-generation sequencing, large fragment copy number variation analysis, SNP typing, qPCR analysis and gene chip analysis.Bring your own instruments and reagentsPCR instrument Reaction tubes: low adsorption tubes recommended Gun Heads: High quality filtered gun heads are recommended Microcentrifuge, vortex mixercaveat The sensitivity of this product is very high, the experimental operation should be completed in a positive pressure ultra-clean bench or clean environment, the concentration of the amplification reaction products is high, should be well isolated to avoid aerosol contamination caused by amplification products.Operation flow diagramprocedurePre-experiment preparationSingle cells were obtained by flow cytometry sorting, buffer dilution, micromanipulation and laser microdissection. It is recommended that the cells be washed prior to the experiments with a 1× PBS solution free of Mg2+ and Ca2+, taking care to ensure that the volume of PBS solution in subsequent experiments does not exceed 2 µl. take note of Since the whole experiment is carried out in the same PCR tube and the reaction volume is small, the pipette tip should not touch the liquid in the tube when adding liquid, so as to avoid taking single cells or DNA out of the reaction system; when pipetting, please add the liquid along the wall of the tube carefully and do not blow the liquid in the PCR tube; before the reaction, please centrifuge briefly to make sure that the liquid in the reaction system is mixed evenly. Thaw the cell lysate, pre-amplifier and amplifier on ice before use.cell lysis 1）Mix Cell Lysis Buffer and Cell Lysis Enzyme according to the number of reactions N, shake to mix, centrifuge briefly and set aside.2）Mix single cells with the cell lysis mix in a PCR tube and run the following program.2.
