Embodiment 1273

[0057] Example 1 Detection of 273 cases of skin tissue herpes virus subtype infection

[0058] Samples: 273 cases of skin tissue from Shanghai Dermatology Hospital patients, aged between 5 and 93 years old, male or female, collected different organs or tissues from each patient (choose lesion sites with typical characteristics, such as upper limbs, right feet, On the right, etc., the whole layer of skin was cut, including the epidermis and dermis), and the main pathological diagnosis was skin tumor, nevus cell nevus, seborrheic dermatitis or keratosis, eczema, etc.

[0059] 1. DNA extraction

[0060] The above-mentioned skin tissue samples were collected, placed in test tubes, and stored at -80°C. DNA was extracted using a DNA extraction kit (TissuegDNA kit, Biomiga), and the quality (OD260 / 280) and concentration of DNA extraction were initially detected.

[0061] The specific operation is as follows:

[0062] (1) Rinse the sample with PBS solution after taking it out, put ...

Embodiment 21

[0085] Example 2 Detection of herpes virus infection in 1 case of varicella patient (plasma)

[0086] Samples: From Huashan Hospital of Fudan University, samples were taken from female chickenpox patients.

[0087] 1. Using the HMW method to extract DNA from the patient's plasma

[0088] (1) Add 400ul HMW buffer to resuspend plasma (180ul), add 40ul 10% SDS at the same time, 20ul10mg / ul proteinase K, incubate in 60°C water bath for 5h;

[0089] The preparation of HMW buffer is as follows (mix well and store at 4°C):

[0090]

[0091] (2) Add an equal volume of phenol chloroform (1:1), 12000rpm / 5min at 4°C, collect the supernatant, and repeat the operation once;

[0092] (3) Add 1 / 10 volume of sodium acetate, 2 times the volume of ice ethanol, -80°C for 1h, 4°C at 12000rpm / 5min;

[0093] (4) Wash once with 70 ice ethanol, 4°C 12000rpm / 5min;

[0094] (5) Dry in air (20min), dissolve with ddH2O (20ul), and store at -20°C.

[0095] 2. PCR detection

[0096] PCR reaction s...

Embodiment 310

[0105] Example 3 Detection of herpes virus infection in 10 samples

[0106] Samples: From the Shanghai Center for Disease Control and Prevention, each sample was from a patient suspected of being infected with the measles virus.

[0107] 1. DNA extraction

[0108] Take an appropriate amount of sample at -80°C, use a DNA extraction kit (Tissue gDNA kit, Biomiga) to extract DNA, and initially detect the quality and concentration of the DNA extraction, the method is the same as in Example 1.

[0109] 2. PCR detection

[0110] Reaction system and reaction condition are the same as embodiment 1.

[0111] 3. Test results and analysis

[0112] Test results such as image 3 As shown, for HSV-1: 5 samples of simple infection with measles virus were all negative, and 5 samples of mixed infection were all positive; for HSV-2: 5 samples of simple infection with measles virus were all negative, and 5 samples of mixed infection were all negative. Infected samples were all positive; for...

Abstract

The invention discloses a rapid detection reagent for various subtypes of human herpesvirus, which comprises specific amplification of HSV‑1 RL2, HSV‑2 UL28, VZV ORF26, EBV EBNA1, HCMV IE, HHV‑6A or HHV‑6B U22, HHV‑6B U22, HHV‑6A 6A or HHV‑6B IE, the forward and reverse primers of HHV‑7 U95 and KSHV ORF72 and the corresponding internal reference standard; also disclose a kind of rapid detection kit of each subtype of human herpesvirus including above-mentioned detection reagent; also disclose a A rapid quantitative reagent for each subtype of human herpesvirus and a detection and quantitative kit including the above detection reagent. The invention can quickly and effectively identify and diagnose various subtypes of clinical samples in the early stage of infection from different sources, and can also perform quantitative calculation of virus copy numbers conveniently and accurately, and has high clinical diagnostic value.

Description

technical field [0001] The invention belongs to the field of biochemistry and molecular biology, relates to a detection reagent and a kit, in particular to a reagent and a kit for rapid detection and quantification of various subtypes of human herpesviruses. Background technique [0002] Human herpesvirus (HHV) is a double-stranded DNA virus, which can be divided into three subfamilies α, β, and γ according to its conserved structural protein sequence, and can be divided into 8 subtypes according to its genome characteristics, namely, herpes simplex virus 1 , type 2 (HSV-1 / 2), varicella-zoster virus (VZV), Epstein-Barr virus (EBV), human cytomegalovirus (HCMV), herpesvirus 6, 7 (HHV-6A / 6B / 7) and Kaposi's sarcoma virus (KSHV). It is known that human herpes virus has a high infection rate in the population, and can invade various tissue cells of the human body, thereby causing skin, mucous membrane, lymph, liver, lung, reproductive or nervous system and other organ infections...
