PCR Assay Kit

This kit is used for qualitative detection of respiratory virus nucleic acids in clinical samples. Respiratory virus (RV) is a virus that causes respiratory infections in humans. This kit can be used to detect 12 virus types, including influenza A, influenza B, respiratory syncytial virus, human metapneumovirus, human bocavirus, adenovirus, parainfluenza virus 1/2/3/4, coronavirus and human rhinovirus.

The TianLong Respiratory 15 Types Virus Nucleic Acid Multiplex Detection Kit (0.2mL Pre-filled) is intended to detect 15 respiratory viruses nucleic acid qualitatively using Real-time Reverse Transcription Polymerase Chain Reaction (Real-time RT-PCR/PCR) method.

Foodborne diseases have become a major public health problem in both developed and developing countries. Bacteria, viruses and parasites can all cause foodborne diseases, among which Salmonella and Shigella are the main bacteria causing foodborne diseases.

The TianLong SARS-CoV-2 Nucleic Acid Detection Kit is intended for the qualitative detection of SARS-CoV-2 nucleic acid by Direct Real-time reverse transcription Polymerase Chain Reaction (Direct Real-time RT-PCR) method.

The kit is used for in vitro qualitative detection of group B streptococci in genital secretions and rectal secretions samples.

Tianlong Real Time PCR Detection Kit is developed by our RD independently, after long period clinical verification, it has advantages such as high sensitivity , enhanced specificity, quick response and easy operation, high sample coverage and low undetected rate, it plays an important role in viral diagnostic. Besides, Tianlong real time PCR detection kit, used cooperatively with Tianlong nucleic acid extractor and PCR detection machine , made great contribution to the prevention and control of various major epidemics such as avian flu, Ebola, MERS, African swine fever and neonatal pneumonia.

The TianLong Human Adenovirus (Ad) Nucleic Acid Detection Kit is intended for the qualitative detection of diarrhea viruses nucleic acid by Real-time Polymerase Chain Reaction (Real-time PCR) method.

The TianLong Bacillus Pertussis Nucleic Acid Detection Kit is intended for the qualitative detection of Bacillus pertussis nucleic acid by Real-time Polymerase Chain Reaction (Real-time PCR) method.

K-ras gene, located on chromosome 12p12.1, is one of the important oncogenes. It encodes a 21kD KRAS protein and participates in intracellular signal transduction, mainly including RAS/PI3K/PTEN/ Akt and RAS/RAF/MEK/ERK signal transduction pathway. These transduction pathways are currently the hotspots in the research of tumor-targeted drugs. Targeted drugs have pharmacological effects by inhibiting these pathways. Studies have shown that K-ras gene mutations exist in non-small cell lung cancer and colorectal cancer, and mutation of K-ras occurring at codon 12 and 13 which could cause KRAS protein to mutate and remain activated can render the drug ineffective.According to the 2010 edition of the Chinese Oncology Clinical Practice Guidelines, 101 patients with bronchioloalveolar carcinoma of the lung adenocarcinoma subtype received first-line treatment with erlotinib alone in a retrospective study.
