A plant tissue culture lab requires a controlled, sterile environment and specific tools and equipment to ensure the successful growth of plant cells, tissues, or organs in a nutrient medium. Here's a list of the essential tools and equipment typically needed in such a lab:
1. Basic Lab Setup
Laminar Air Flow (LAF) Cabinet: A sterile work area where tissue culture manipulations are done to prevent contamination.
Autoclave: Used to sterilize media, glassware, and instruments through high-pressure steam.
Incubator or Growth Chamber: Maintains controlled temperature, humidity, and light conditions to promote plant growth.
Hot Air Oven: Used to dry and sterilize glassware at high temperatures.
Distillation Unit or Deionized Water System: To provide pure water for preparing media and cleaning.
2. Glassware and Plasticware
Petri Dishes: For culturing small tissues or cells.
Culture Bottles/Flasks: Used for growing plant tissue in a sterile environment.
Test Tubes and Culture Tubes: For the culture of explants and plantlets.
Beakers and Measuring Cylinders: For measuring liquids and preparing media.
Erlenmeyer Flasks: To prepare and store culture media.
3. Media Preparation
pH Meter: For adjusting the pH of the culture medium to ensure optimal growth conditions.
Balance (Analytical and Top Pan): For weighing chemicals precisely when preparing media.
Magnetic Stirrer with Hot Plate: Used to dissolve media components evenly while heating.
Dispensing Pipettes or Pipette Guns: For accurate measurement and transfer of liquids.
4. Sterilization and Disinfection
Ethanol (70% Solution): Used for surface sterilization of work surfaces and tools.
Forceps and Scalpels: For handling explants and cutting plant tissues, which need to be sterilized before use.
Bunsen Burner or Spirit Lamp: To flame sterilize tools between uses.
5. Growth Media and Supplies
Murashige and Skoog (MS) Medium or Other Nutrient Media: The nutrient solution where plant tissues grow.
Sucrose: A sugar source that provides energy for plant tissues in culture.
Agar: Used to solidify the culture medium for growing plant tissues.
Growth Hormones (e.g., Auxins, Cytokinins): To stimulate root or shoot formation depending on the stage of tissue growth.
6. Microscopy and Observation
Stereo Microscope (Dissecting Microscope): Used to observe small plant tissues and explants during the culture process.
Compound Microscope: For detailed observation of cellular-level processes.
7. Cutting and Handling Tools
Scissors and Surgical Blades: To cut plant tissues for culture.
Micropipettes: For measuring and adding small volumes of liquid, including hormones and vitamins.
Tongs and Spatulas: For handling explants, tools, or media ingredients in the sterile area.
8. Miscellaneous Supplies
Parafilm or Plastic Wrap: To seal culture vessels and prevent contamination.
Labels and Markers: To label culture containers for tracking growth.
Gloves, Masks, and Lab Coats: Personal protective equipment to maintain sterility.
9. Lighting and Temperature Control
Fluorescent or LED Grow Lights: To provide the required light for photosynthesis in plant cultures.
Thermometers and Hygrometers: To monitor temperature and humidity levels in the growth chamber or incubator.
These tools and equipment are essential for setting up a functional plant tissue culture lab. The key factor is maintaining a sterile environment to ensure that plant tissues grow without contamination from bacteria or fungi.
