Embodiment Construction

[0013] One aspect of the present invention relates to a kit, comprising a kit for amplifying STR loci D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, CSF1PO, FGA, TH01, TPOX, vWA, Penta E, PentaD and Amelogenin One or more of the 16 pairs of upstream and downstream primers, the sequences of the 16 pairs of upstream and downstream primers are shown in SEQ ID NO: 1-32.

[0014] The kit of the present invention involves 16 pairs of upstream and downstream primers. The above 16 pairs of upstream and downstream primers have the advantages of good specificity and high amplification efficiency. Specific amplification and cross-reaction avoid the impact of non-target products on the typing results. At the same time, the amplification efficiency is high and the detection signal is strong. On the one hand, it can shorten the PCR amplification time. On the other hand, due to the high detection signal, it can be quickly Accurate detection of PCR products and STR typing...

Abstract

The invention provides a kit and a using method thereof. The kit comprises one or more pairs of 16 pairs of upper and lower primer pairs for amplifying STR sites D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, CSF1PO, FGA, TH01, TPOX, vWA, Penta E, Penta D and Amelogenin, and the sequences of the 16 pairs of upstream and downstream primer pairs are shown in SEQ ID NO: 1-32. The16 pairs of upstream and downstream primer pairs related to the above-mentioned kit and the using method have the advantages of high specificity and high amplification efficiency, and can quickly andaccurately classify 16 STR sites.

Description

technical field [0001] The present invention relates to the field of STR detection, in particular to a kit and a method for using the same. Background technique [0002] Short tandem repeats (short tandem repeats, STRs), also known as microsatellite DNAs (microsatellite DNAs) or simple sequence repeats (simple sequence repeats, SSRs), are a type of tandem repeats with several bases as the core unit widely present in the human genome. The resulting DNA sequence. The STR locus is widely distributed, and there is one in every 100-200kb in the human genome on average, and its core repeating unit is generally 2-6 bases, and the number of repeats is between 10-60 times. Due to the difference in the number of repeating units between different individuals, there is a high polymorphism, and this polymorphism follows the Mendelian inheritance law in the genetic process, so STR genetic analysis is widely used in forensic individual identification, kinship identification, Population g...
