Introduction to Cell Proliferation Assays

Cell proliferation refers to the process by which cells divide and multiply. Assessing cell proliferation is crucial in cancer research, drug development, and understanding fundamental biological processes. Various techniques and assays are used to measure cell proliferation, each with its unique advantages and applications.

Types of Cell Proliferation Assays at ACME Research Solutions

MTT Assay (Most Common Assay for Cell Proliferation Assay)
- Measures metabolic activity as an indicator of cell viability and proliferation.
- Utilizes the reduction of MTT reagent to formazan by mitochondrial enzymes.
BrdU Incorporation Assay
- Measures DNA synthesis by incorporating BrdU (bromodeoxyuridine) into newly synthesized DNA strands.
- Detected using anti-BrdU antibodies.
Ki-67 Staining
- Detects the presence of Ki-67 protein, a marker associated with cell proliferation.
- Commonly used in immunohistochemistry and flow cytometry.
Cell Counting
- Directly counts cells using a hemocytometer or automated cell counters.
- Simple and straightforward but may not distinguish between live and dead cells.
CFSE Staining
- Tracks cell division by staining cells with carboxyfluorescein diacetate succinimidyl ester (CFSE).
- Used in flow cytometry to measure the dilution of CFSE signal as cells divide.

Detailed Procedure for MTT Assay (Cell Proliferation Assay)

The MTT assay is one of the most commonly used methods for assessing cell proliferation due to its simplicity and reliability. Below is a step-by-step procedure for performing an MTT assay.

Materials Needed

MTT reagent (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide)
Culture medium
Dimethyl sulfoxide (DMSO)
96-well culture plates
Cell lines of interest
Incubator (37°C, 5% CO₂)
Microplate reader

Procedure

Cell Seeding
- Seed cells into a 96-well plate at a density appropriate for your cell line (typically 5,000-10,000 cells per well).
- Incubate the plate for 24 hours to allow cells to adhere and reach exponential growth phase.
Treatment Application
- Treat the cells with various concentrations of the test compound or control.
- Incubate for the desired time period (usually 24-72 hours).
MTT Addition
- Add 10 µL of MTT reagent (5 mg/mL in PBS) to each well.
- Incubate the plate for 3-4 hours at 37°C. During this time, the MTT reagent is reduced to formazan by metabolically active cells, forming a purple precipitate.
Formazan Solubilization
- Carefully remove the culture medium without disturbing the formazan crystals.
- Add 100 µL of DMSO to each well to dissolve the formazan crystals.
- Gently shake the plate to ensure complete solubilization.
Absorbance Measurement
- Measure the absorbance of each well at 570 nm using a microplate reader.
- The absorbance values correlate with the number of viable, proliferating cells.
Data Analysis
- Analyze the absorbance data to determine cell proliferation rates.
- Compare treated samples with control to assess the effect of the test compound on cell proliferation.

Applications of Cell Proliferation Assays

Cell proliferation assays are used in various research and clinical settings, including:

Cancer Research: Understanding tumor growth and testing anti-cancer drugs.
Drug Development: Screening for compounds that promote or inhibit cell proliferation.
Toxicology Studies: Assessing the cytotoxic effects of chemicals and environmental agents.
Basic Research: Investigating fundamental cellular processes and mechanisms.
