Market leading in vitro diagnostic products

Non-inactivation type disposable virus sampling kit is a sampling VTM for collecting virus specimens, such as saliva, nasal swab and pharyngeal swab which may contains flu virus, SARS-CoV-2, etc. The preservation solution uses the PBS buffer formula, adding fetal bovine serum (FBS) and antibiotics. It has a good preservation effect, prevents bacterial and fungal contamination, and can maintain the activity of the virus for nucleic acid detection, virus isolation and other purposes.

LSP Viral Transport Medium (VTM) is a non-propagating transport culture medium intended for transport of clinical material from the collection site to the laboratory for testing. This medium is designed to sustain the viability of viruses, chlamydia and mycoplasma for research, diagnostic tests, molecular biology techniques and conventional cell culture methods and may also be used for the short-term storage of samples.

LSP VTM ensures proper collection, transport and storage of clinical specimens containing upper respiratory viruses, in particular of SARS-CoV-2, the virus responsible for COVID-19. The medium is formulated to preserve genome (RNA) integrity of the virus while suppressing growth of bacteria and fungi that may be present in clinical samples from the human respiratory system.

The constituents are designed to provide an isotonic solution containing protective protein, antibiotics to control microbial contamination, and one or more buffers to control the pH.

Liquid transport media are used primarily for transporting swabs or materials released into the medium from a collection swab. Liquid media may be added to the specimens when inactivation of the viral agent is likely and when the resultant dilution is acceptable. This Viral Transport Medium (CDC) is manufactured to current Center for Disease Control and Prevention (CDC) protocol SOP SOP#: DSR-052-01.

Applications:

For the collection of:

• virus samples (COVID-19, Respiratory Syncytial Virus, Influenza A and B, Herpes Simplex I and II, Cytomegalovirus, Echovirus, etc.).
• Chlamydia tachomatis and pneumoniae.
• Mycoplasma hominis and pneumonia.
• Ureaplasma urealyticum.
• Enzyme Immuno Assays (EIA).

The LSG VTM is NOT an inactivating medium.

Inactivir® PLUS is again a guanidine-based buffer that uses an alternate REACH-compliant detergent. Under REACH regulations Triton X-100 should not be used from 2021 onwards and is only in current large-scale use due to pandemic exclusions. This buffer is REACH compliant and features an improved buffer system for stabilisation of RNA in samples. The Inactivir PLUS kit is suitable for the collection of virus specimens, such as saliva, nasal swab and pharyngeal samples, demonstrating complete viral inactivation of SARS nCoV-19, Ebola, Influenza A & B, RSV and a wide range of other viruses. The preservation solution protects the viral nucleic acid from degradation for one week at room temperature (15 ~ 25°C). Inactivir PLUS is compatible with many lysis buffers in DNA/RNA extraction kits.

Inactivir® SD LITE is a non-guanidine buffer that is based on established inactivation principles used in production of human products for several decades with no evidence of viral transmission through those products in the entire timescale. Specific testing has shown inactivation of a wide range of viruses including SARS nCov-19. This buffer is designed for Point of Care (POC) or near-POC testing, with minimal additional components that could interfere with downstream testing. It does not stabilise RNA within samples and is suited for immediate testing use. This buffer is used to rapidly release nucleic acids from nasopharyngeal swabs, oropharyngeal swabs and saliva samples. After nucleic acid is released, it can be directly used as a template for nucleic acid amplification, such as PCR, qPCR, RT-qPCR and isothermal amplification without nucleic acid purification. The lysis material contained in the storage solution in the sample tube can inactivate the virus quickly and preserve the RNA.

Inactivir® SD COMPLETE has the same non-guanidine inactivation system as Inactivir SD LITE, but additionally contains buffer components that inactivate nucleotide degrading enzymes including RNAses. It therefore stabilizes samples to allow remote testing away from the site of sampling.

Inactivir® SDI includes an additional chaotrope along with the non-guanidine inactivation system presented in Inactivir SD LITE. This provides excellent stability for samples and allows the sample to be used directly in silica-based purification systems.

The LSG NAP buffer is a transport medium for preserving nucleic acids that can be stored reliably at room temperature after sampling.

NAP Transport medium can release objects from the head of the sample collection swab into the Nucleic acid preservation solution. The sample can be safely transported through the use of a sample transport container, and the structure is convenient and centrifugal separation can be used using a self-standing mechanical tube.

This product contains antibiotic/antimycotic to protect against the grown of bacterial and fungi.

Simply place the samples in the nucleic acid preservation medium. DNA will remain stable at room temperature for five months and RNA will remain stable for a week.
