A method for transferring a foreign substance includes the steps of: preparing a construct for transferring a foreign substance that contains a carrier peptide fragment including either the amino acid sequence KKRTLRKNDRKKR (SEQ ID NO. 1) or an amino acid sequence formed by the substitution, deletion, and/or addition (insertion) of 1, 2, or 3 amino acid residues in the amino acid sequence, and a foreign substance of interest that is bonded to the N-terminus and/or C-terminus of the carrier peptide fragment; supplying the construct for transferring a foreign substance to a test sample that contains a target eukaryotic cell; and incubating the test sample that has been supplied with the construct for transferring a foreign substance to thereby transfer the construct into the eukaryotic cell in the test sample.

The present invention provides a technology which can perform a precise restoration to a distribution of original information by carrying out an iterative calculation using only a distribution of degraded information. The method according to the present invention performs the restoration to original information based only on degraded information. The method according to the present invention considers the distribution of the degraded information and the distribution of the original information as distributions of probability density functions, and considers a transfer function of a transfer system as a probability density function of a conditional probability. The most probable estimations of the distribution of the original information with respect to the distribution of the degraded information and the most probable estimations of the distribution of the transfer function are alternately carried out to finally restore the original information by means of the iterative calculation based on the Bayes' theorem for probability density functions.

摘要:
The present invention provides methods for selecting artificial promotor candidates that reduce the number of promotors required to be evaluated by actual experimentation when designing artificial promotor candidates that are potentially effective for structural genes. In these artificial promotor candidate selection methods, a randomly selected nucleotide sequence is joined upstream of a structural gene (S1). Next, nucleotides are extracted in a predetermined pattern from a designated region containing at least the transcription start site of the joined nucleotide sequence, thereby generating a virtual amino acid sequence, and an index curve is generated from the virtual amino acid sequence (S2, S3). Then, the nucleotide sequence joined upstream of the structural gene is selected as an artificial promotor candidate if the index curve exhibits a sign change near the transcription start site (S4).
