TOMSK, Sep 17 – RIA
Tomsk. The Engineering Chemical Technology Center (ECTC) of Tomsk State University (TSU) received a patent for the Lexstil28 fixative developed jointly
with scientists of Siberian State Medical University (SSMU) – a non-toxic analogue
of formalin needed for human tissue studies, the TSU press service reported on
Friday.
"The fixative
for histological studies Lextil28 - an analogue of formalin solution, developed
by chemists of Tomsk State University together with ECTC and SSMU – has been
patented... Technical tests of the composition are now underway, after which
its safety will be once again confirmed by toxicological tests. Then the
fixative will be taken out for clinical tests", the report said.
It is noted that
Lextil28 is a medical product which is not inferior to 10% formalin solution in
terms of fixation of tissue samples. Unlike carcinogenic formalin, which is a
substance of the second class of danger, the development of the Engineering
Chemical Technology Center is safe for humans and does not emit toxic fumes.
"We are now
thoroughly preparing the paperwork – the accompanying documents and test
materials - without which the product will not be sold. The competence of our
engineers allows us to assemble as complete a set as possible for the
convenience of those who will promote our customer's product," director of
the TSU ECTC Alexey Knyazev is quoted.
According to him,
Lextil28 has been tested in Krasnoyarsk, Novosibirsk and Tver State Medical
Universities, as well as in the forensic medical bureau. Now, in order to
participate, for example, in state procurements, the drug must undergo state
registration – this was the key recommendation of the experts who conducted the
trials.
The development of a
new reagent for fixing human organ and tissue parts in biopsies was announced
in 2019. The non-volatile and safe for the specialists using it will be in
demand in forensic medicine and medical organizations, adds the press service.
It was previously
reported that the ECTC developed a safe formalin analogue, Adolfix, in 2018,
which is used for fixing museum exhibits, transporting biomaterials, and making
preparations for medical students.
