Abstract:

Abstract Background and Objectives Evaluation of cell survival is important in cellular studies and the result is decisive for the application of the test substance. Different methods are used to evaluate cell survival and the correlation between methods is important. Here, Vero cell line was used to evaluate the effects of HSV-1 virus on cell survival. Cell survival after HSV-1 infection using sensitive colorimetric methods of 3-, 4-, 5-dimethylthiazole-2-yl, -2, 5-diphenyltetrazolium bromide (MTT), and Trypan Blue on Vero cell line was examined.   Materials and Methods A qualitative study was performed on Vero cell line infected with HSV-1 virus with logarithmic dilutions10-1 to 10-5 dilutions and time intervals of 0, 4, 8, 18 and 24 hours and the s in DMEM containing 2% Fetal bovine serum (FBS). Then cell viability by MTT and Trypan tests was examined . The survival percentage was used to plot the survival curve of the assays.   Results Different viral dilutions were used to determine the infectious dose of 50% (TCID50) of HSV-1virus with invert microscope. Acyclovir at a concentration of 50 mg/mL was compared as drug control for MTT and Trypan Blue. The results of regression analysis showed cell survival. Linear, positive and significant correlation was observed between the methods that showed a correlation between MTT and Trypan Blue methods (p< 0.001, r = 0.9(   Conclusions  The results showed that both methods can be used to determine cell survival and the results of MTT can be confirmed by Trypan Blue method.

Comparison of MTT, trypan blue, and clonogenic assay, to determine the viability in human anaplastic thyroid cancer cell line

Background: Evaluation of cell viability is momentous in pharmacologic and oncological research. Cell viability evaluation determines cell sensitivity and consequently treatment outcome. Various methods are available to determine cell survival. Each of these methods evaluates different endpoints. Accordingly, determining the correlation between these methods is important. In this study, in orde...

investigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances

در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

Evaluation of MTT and Trypan Blue assays for radiation-induced cell viability test in HepG2 cells

Background: &nbsp;Cell viability is an important factor in radiation therapy and thus is a method to quantify the effect of the therapy. Materials and Methods: The viability of human hepatoma (HepG2) cells exposed to radiation was evaluated by both the MTT and Trypan blue assays. The cells were seeded on 96 well-plates at a density of 1 x 104 cells/well, incubated overnight, and irradiated with...
