Mammalian sperm motility has traditionally been analyzed to determine fertility using computer-assisted semen analysis (CASA) systems. To develop low-cost and robust male fertility diagnostics, we created a paper-based MTT assay and used it to estimate motile sperm concentration. When porcine sperm motility was inhibited using sperm enzyme inhibitors for sperm enzymes related to mitochondrial a...

Neurocysticercosis (NCC) is caused by the larval form of the pork tapeworm Taenia solium when lodged in the central nervous system (CNS). Clinical diagnosis of NCC is complicated due to its polymorphic manifestations with no specific signs or symptoms. A wide range of serological assays and neuroimaging modalities are used for its diagnosis. The aim of the present study was to evaluate the MTT ...

The MTT (3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyltetrazolium bromide) assay is a classical method for screening cytotoxic anti-cancer agents. Candidate drugs from the MTT assay need in vivo models to test their efficiency and to assess the absorption, distribution, metabolism, excretion, and toxicity of the drugs. An in vivo screening model could increase the rate of development of anti-cancer...

Multiple in vitro tests are widely applied to assess the anticancer activity of new compounds, including their combinations and interactions with other drugs. The MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay is one of the most commonly used assays to assess the efficacy and interactions of anticancer agents. However, it can be significantly influenced by compounds t...

introduction: sperm viability test is important in diagnosis and treatment of male infertility. the common test is e&n; and host which they are based on membrane permeability and integrity. the aim of this study was to evaluate mtt assay as a sperm viability test based on mitochondrial activity. materials and methods: washed sperm samples were co-incubated with mtt in different media and differ...

For studying proliferation and determination of survival of cancer cells after irradiation, the multiple MTT assay, based on the reduction of a yellow water soluble tetrazolium salt to a purple water insoluble formazan dye by living cells was modified from a single-point towards a proliferation assay. This assay can be performed with a large number of samples in short time using multi-well-plat...

Background: Various MTT assay methods are proposed to obtain the cell sur- vival parameters.Objective: Determining the survival curve characteristics of two cancerous cells of interest based on a common and a novel MTT assay method after exposing them to ionizing radiation.Method: A common and a novel MTT assay method were used and compared for obtaining the F10B16 melanoma and 4T1 breast adeno...

ABSTRACT Cyanide (KCN) and paraquat (PQ) are very toxic to mitochondria. In this study the toxicity of KCN and PQ in the isolated rat liver mitochondria was determined using the MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] assay and JG-B (Janus green B) assay by multiwell scanning spectrophotometry. JG-B was used not only for the vital staining of mitochondria, but also fo...

The MTT method for rifampicin and isoniazid susceptibility testing of Mycobacterium tuberculosis was developed by using bacterial suspension prepared from colonies on solid media. The MTT tube assay in 1 ml Middlebrook 7H9 broth was completed within 4 days for rifampicin (RMP) and within 7 days for isoniazid (INH). When MTT assay results with 279 M. tuberculosis clinical isolates were compared ...
