  • Publication number: 20180031513
    Abstract: The present invention relates to a method for detecting an undifferentiated pluripotent stem cell, and a cell-chip using the same. Since the cell chip-based quantitative analysis method of the present invention does not use antibodies, unlike flow cytometry or real-time PCR which has been conventionally used for the quantitative analysis of pluripotent stem cells, there is an advantage in that it is possible to conveniently and rapidly perform quantitative analysis, and since the function of cells is not affected even after analysis, it is possible to recover and use the cells used in the analysis.

  • Patent number: 5450420
    Abstract: An error correction system including a syndrome modifier for receiving a syndrome and operating the equation ##EQU1## where i is an integer greater than or equal to zero, for transforming the syndrome into a new syndrome; an n-1 error correction circuit for receiving the syndromes modified by the syndrome modifier for n-1 error correction, a counter for varying the K value if the n-1 error correction fails; a circuit for outputting an .alpha..sup.K value corresponding to the K output signal of the counter, to the syndrome modifier, an error value operation circuit for receiving the output signal of the n-1 error correction circuit to calculate a substantial error value according to the equatione.sub.i =e'.sub.i /(1+.alpha..sup.i-k)where i is an integer greater than or equal to zero; and an adder for receiving and adding the output signal and the syndrome from the error value operation circuit, to perform a final error correction.
