Cell services typically refer to cell culture related services provided in laboratories for scientific research, drug development, biotechnology applications, and other purposes. A cell line is a group of genetically identical cell populations obtained through asexual reproduction from a single cell. Cell lines can be immortalized (able to be passaged for a long time) or limited (can only be passaged a certain number of times).

Service Name | Characteristics and Applications |
Cell line establishment service | Cell line establishment services typically refer to the isolation of individual cells from tissue samples under laboratory conditions using specialized techniques and equipment, and their cultivation into a population of cells capable of long-term survival and division in vitro. This service is widely used in basic life science research, drug screening, gene therapy, and other fields. |
Single cell cloning screening service | Single cell cloning screening service is a service that uses single-cell cloning technology to screen cell clones with specific characteristics from a group of cells during the establishment of a cell line. This service is crucial for ensuring the uniformity and stability of cell lines, especially in genetically engineered cell lines. |
Cell STR identification service | STR is formed by repeatedly connecting the ends of core repeat units. The core sequence structure of each STR is the same, with a length of 2-6 bp, but the number of repeat units and the length of repeat regions are different. Therefore, the distribution of STR varies among different races and populations, constituting STR genetic polymorphism. The number of repetitions at a homologous STR locus varies among individuals, so like fingerprint recognition, STR locus analysis can also be used to identify individuals. By identifying specific sequence repeats of an individual's genome at specific loci, their genetic profile can be created. Based on this, STR analysis has become an important identification and analysis method, applied in fields such as forensic science, paternity testing, and cell identification. |
Cell proliferation capability service | Cell proliferation is one of the important physiological functions of living cells and an important life characteristic of organisms. The proliferation of cells is the basis for the growth, development, reproduction, and genetics of organisms. Normal cells have vigorous metabolism, and the succinate dehydrogenase in their mitochondria can reduce tetrazolium salts (such as MTT, XTT, WST-1, and WST-8) into purple crystalline substances that deposit around the cell. Then, the OD value can be read by an enzyme-linked immunosorbent assay (ELISA) reader to detect the state of cell proliferation. |
