質問

1–10/10 質問  
  1. I used 0.05g in 10ml then syringe it and add 40ml. My question is how to calculate the percentage of viable cells? I used DMSO after MTT solution

    1 回答
    1. MTT is typically used for the semi-quantitative colorimetric measurement of cell viability. This analysis is performed in a multi-well format which screens for the viability of any given compound at any given concentration. The percentage of viable cells cannot be determined using this method. After adding a stop reagent, in this case DMSO, the formazan crystals will be dissolved, making manual counting a challenge, at best. When used in a multi-well plate format, cells are incubated, a stop solution is added, and the plate is read spectrophotometrically at 570 nM. Please see the link below to review the product datasheet:
      https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/product/documents/305/017/m2128pis.pdf

      For additional information, see the link below to the MTT kit protocol for product TOX1, a cytotoxicity kit that utilized MTT:
      https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/product/documents/333/177/tox1bul.pdf

      To measure cell viability as a percentage of an entire population, microscopic methods may be of interest. Reagents such as Trypan Blue allow for the clear identification of viable and non-viable cells. To review more information regarding this method, please see the link below:

  2. What is the recommendation volume of 5 mg/ml of thiazolyl blue tetrazolium blue (in uL) per well to use for MTT assay? 

    1 回答
    1. Instructions for use are not provided for this product. However, there is an in vitro toxicology assay kit MTT based available. The catalog number is TOX1-1KT. In the kit, 15 mg of solid MTT is supplied. This is resuspended with 3 ml of media or a balanced salt solution without phenol red or serum. The link shared below will list the complete procedure

  3. What can be used to solubilize MTT formazan (the product of the Thiazolyl Blue Tetrazolium Bromide - MTT reaction)?

    1 回答
    1. Mitochondrial dehydrogenases of viable cells cleave the tetrazolium ring of the MTT, yielding purple MTT formazan crystals. These crystals are not soluble in aqueous solutions; they may be dissolved in acidified isopropanol (0.1 N HCl in anhydrous isopropanol). If this does not lyse the cells, Triton X-100 can be added to the acidified isopropanol. A typical working concentration is 10% Triton X-100 (i.e., 1 volume of 100% Triton X-100 + 9 volumes of acidified isopropanol).

  5. Why is a reference wavelength used for data analysis of Thiazolyl Blue Tetrazolium Bromide (MTT)?

    1 回答
    1. The reference wavelength (630-690 nm) is used to adjust for the optical variation in the wells of the plate.  It also corrects for dust and fingerprints that can be present.  The assay is read at 570 nm.  The reference wavelength needs to be far enough away from the assay wavelength so as not to affect those values.

  6. What can be used to make a solution of Thiazolyl Blue Tetrazolium Bromide (MTT)?

    1 回答
    1. We test the solubility of MTT in water at a concentration of 5 mg/mL.  For the MTT viability assay, we dissolve Product No. M5655 at a concentration of 5 mg/ml in RPMI-1640 without phenol red. This medium is available as a powder (Product No.R8755) or liquid (Product No. R7509). MTT can be solubilized in any culture media or balanced salt solution that does not contain phenol red as a pH indicator.

  7. How can I store solutions of Thiazolyl Blue Tetrazolium Bromide (MTT)?

    1 回答
    1. Reconstituted MTT solution is stable for at least 6 months when stored frozen (-20 °C). Storage of reconstituted MTT solution at 2-8°C for more than 2 weeks may cause decomposition and yield erroneous results.

  8. What type of multi-well plate should be used for the Thiazolyl Blue Tetrazolium Bromide (MTT) assay?

    1 回答
    1. It is recommended that flat bottom multi-well plates be used for the MTT assay. The use of tissue culture treated plates is only important if necessary for good cell growth.  If cells are grown in larger plates, the supernatant after cell lysis can be transferred to a 96 well plate for reading.

  10. Is the MTT assay quantitative?

    1 回答
    1. The MTT asay is a method to assess cell viability.  This assay is a semiquantitative assay. The assay is used to compare the viability changes in treated cells to untreated cells. The absorbance is indicative of the cell number. The higher the absorbance, the greater the number of viable cells present. Most researchers compare the absorbance of the two samples as a ratio (ABS treated cells/ABS untreated cells) to get a fold increase/decrease in cell number.
