Testing against enveloped viruses as a replacement for the currently unavailable commercial test strategy against 2019-nCov / SARS-CoV-2 Since the new SARS-CoV-2 virus is one of the enveloped viruses, INVITRO-CONNECT GmbH offers testing of various surfaces and disinfectants against the Vaccinia Ankara Virus (MVA) as a reference virus for enveloped viruses, as well as against the bovine coronavirus , which, like SARS-CoV-2, belongs to the genus Betacoronavirus. In addition to standard tests for surfaces in accordance with ISO 21702 (smooth surfaces) and ISO 18184 (rough surfaces) as well as suspension tests for the disinfectant area (EN ISO 14476/16777), other tests are also offered on request (see below). Named tests are currently the state-of-the-art test methods for testing against 2019-nCov / SARS-CoV-2, as there is currently no specific test procedure against the 2019-nCov / SARS-CoV-2 virus itself.

Determination of skin sensitization potential is a critical endpoint in the safety assessment of raw materials, chemicals, mixtures and formulations. Although the Guinea Pig Maximization Test (GPMT) and Local Lymph node assay (LLNA) have historically been used to address this adverse effect, in vitro assays have been developed and validated in order to replace these resource-intensive animal tests. INVITRO-CONNECT GmbH offers various test strategies without animal testing for examining skin sensitization: - Direct Peptide Reactivity Activation Assay (DPRA, OECD 442C) - ARE-Nrf2 Luciferase Keratinocyte Activation Test Method (OECD 442D) -Human Cell Line Activation Test (h-CLAT, OECD 442E) -Kinetic Direct Peptide Reactivity Assay (kDPRA) -Myeloid U937 Skin Sensitization Test (MUSST / U-SENS) -and more Fast Project Execution: personal - competent - reliable --> contact@invitro-connect. - More than 80 Test Laboratories - Product Safety - Regulatory Service -

- OECD 431 - Human Skin Corrosion: "In Vitro OECD 431: Reconstructed Human Epidermis Test Method, in vitro Test - Skin Corrosion in the regulatory hazard classification and labeling context is defined as the production of irreversible damage to skin, generally evident as necrosis through the epidermis and into the dermis, following a defined chemical exposure. The In Vitro Skin Corrosion Test is an in vitro, non-animal test designed to identify those chemicals and mixtures capable of inducing skin corrosion (UN GHS Category 11), and in some cases to partially subcategorize corrosives into UN GHS Sub-Categories 1A or 1B and 1C (ie., the current test methods do not effectively discriminate between UN GHS Sub-Categories 1B and 1C).
