Embodiment 1

[0041] Establishment of rapid detection of sika deer nucleic acid by LAMP method

[0042] 1 Experimental protocol

[0043] 1.1 Materials

[0044] 12 antler samples (0740, 0741, 0742, 0743, 0744, 0745, 0746, 0747, 0748, 0749, 0750, 0751) were purchased from the market, among which, 0748 was a red deer sample, 0749 was a reindeer sample, and added Serum samples from pigs, ducks, chickens, and bovines are used as samples to be tested.

[0045] 1.2 Instruments and reagents

[0046] LAMP method ribonucleic acid amplification kit (DNA Amplification Kit), EIKEN CHEMICAL CO., LTD, Tochigi, Japan;

[0047] LAMP reaction tube (Reaction Tube), Japan Eiken Chemical Co., Ltd.;

[0048] Visible dye (Te), Beijing Haitai Zhengyuan Biotechnology Co., Ltd.

[0049] Real-time turbidimeter La-320C, Japan Eiken Chemical Co., Ltd.

[0050] 1.3 Method

[0051] 1.3.1 Preparation of Target template target template

[0052] The target template was obtained by extracting nucleic acids from 12 ve...

Embodiment 2

[0182] Sensitivity test.

[0183] In order to verify the detection sensitivity of the above method, the nucleic acid of the extracted sample 0743 (concentration: 76ng / μl) was diluted 10 times, and a total of 7 dilution gradients (sample 0743, 10 -1 , 10 -2 , 10 -3 , 10 -4 , 10 -5 , 10 -6 and 10 -7 ), and double distilled water was used as negative control. Then carry out LAMP reaction according to the method of embodiment 1, adopt turbidity method and Te to detect result.

[0184] The result is as image 3 As shown, LAMP can detect the sixth dilution of sample 0743, and the results of the turbidimetric method are consistent with those of the staining method. Therefore, although the reaction time of the LAMP amplification system is slightly slower, the sensitivity is excellent (because it can detect To the sixth dilution), it is 0.076pg / μl, the sensitivity is enough to meet the actual detection, and the amplification constant temperature time is preferably 65min.

Embodiment 3

[0186] Optimal temperature screening.

[0187] Screen the primers at the optimum temperature, the temperature is from 59-66° C. with a gradient of 1° C., then carry out the LAMP reaction according to the method of Example 1, and use the turbidity method to detect the result.

[0188] Test results such as Figure 4 As shown, it can be seen from the figure that the LAMP reaction occurs first at 60°C, 61°C, and 62°C, and the preferred temperature is 61°C.

Abstract

The invention relates to a sika deer identifying primer and method and application, and belongs to the technical field of species identification. The identifying primer comprises an inner primer FIP:TGTCCTATACACCGATTTATGTGCTGCAAAACACGTGATATAACCT, an inner primer BIP: TGCCCCATGCTTATAAGCATGTGTACGATGAACAACATCATG, an outer primer F3: TCTATGTCCTACTAATTACAC, an outer primer B3: GACTGATTTGACTTAATGCAC, aloop primer LF: ACACGTGTGTCTTAATGTAC, and a loop primer LB: TCCTATCATTTATAGTACATAGT. By the primer, sika deer nucleic acid can be specifically amplified rapidly, and the bottleneck difficulty on identifying cartialgenous.

Description

technical field [0001] The invention relates to the technical field of species identification, in particular to a sika deer identification primer, method and application. Background technique [0002] Antler refers to the unossified and hairy young horns of the sika deer, which is a valuable medicinal material. Antler contains phospholipids, glycolipids, gelatin, hormones, fatty acids, amino acids, proteins, calcium, phosphorus, magnesium, sodium and other ingredients, of which amino acids account for more than half of the total ingredients. Li Shizhen said in "Compendium of Materia Medica" that velvet antler is "good at nourishing kidney and strengthening yang, producing essence and blood, nourishing marrow and strengthening bones", and is a traditional precious Chinese medicine. [0003] However, the authenticity of a large number of antler products on the market is not used, and there are difficulties in identification. A fast, ideal and reliable standardized and standar...
