Transcription Factor E3 (TFE3) is a transcription factor that binds to the MUE3-type E-box sequences involved in TGF-β signalling. Anti-TFE3 staining is the most sensitive and specific indicator of Xp11 translocation renal cell carcinomas. Since alveolar soft part sarcoma (ASPS) is characterized by a specific chromosomal rearrangement resulting in a chimeric transcription factor (ASPSCR1-TFE3), this TFE3 IVD antibody is also a useful diagnostic tool for recognizing ASPS.

Description

Saxitoxins (STXs) are naturally occurring alkaloids produced by some marine dinoflagellates and by strains of various species of freshwater cyanobacteria.  Saxitoxin is one of the prevalent paralytic shellfish toxins (PSTs). It belongs to a family of potent neurotoxins with a molecular weight around 300 Da. Saxitoxin and its derivatives are alkaloids composed of a tetrahydropurine ring system with a highly polar guanidinium group. Due to their significant toxicity, saxitoxins are closely monitored in marine environments where they can accumulate in the food chain during harmful algal blooms (HABs).  An action level of 800ppb, or 80ug per 100grams of shellfish, has been established.

Description

African Swine Fever Virus (ASFV) is a widespread disease which infects members of the pig family(Suidae). Anumberoftick species are believed to be the vector for the disease,as well as being transmitted by raw pork and pig excrement [1]. After firstly being identified in Kenya in 1921, ASFV became endemic in sub-Saharan Africa, with regular outbreaks being reported across Europe, Asia and South America throughout the century [2]. More recently the virus was introduced in Georgia and spread throughout the region, as well as mass outbreaks occurring in China in 2018 [3].
ASFVistheonlymemberoftheAsfaridaefamily.ItisalargeenvelopeddoublestrandedDNA virus of icosahedral morphology with an average diameter of 200nm and isolates contain genomes between 170-190Kbp encoding for up to 167 open reading frames [2]. The morphology of ASFV consist of several concentric domains. An inner core contains the nucleoid coated with a thick protein layered core shell, which is surrounded by an inner lipid envelope , all of which is encompassed by the capsid [2]. ASFV begins its replication cycle in the nucleus of infected cells before moving to the cytoplasm where the majority of the replication takes place [2]. Gene transcription is highly regulated, with distinct classes of mRNA identified to accumulate at early, intermediate and late transcripts of the virus [2]. The disease induces acute haemorrhagic disease within its hosts, causing high fevers and skin haemorrhages, with death often occurring within ten days of clinical symptoms appearing [4].
