Standard Operating Procedure (SOP) describes the guidelines for the use of Streptozotocin in rodents.
1.0 Purpose:
This Standard Operating Procedure (SOP) provides guidelines for the safe and effective use of streptozotocin (STZ) in rodents. Streptozotocin is a cytotoxic compound commonly used for the induction of diabetes in animal models. This SOP aims to ensure the welfare of animals and promote consistent and reproducible research outcomes.
2.0 Scope:
This SOP applies to all personnel involved in handling and administering streptozotocin to rodents within the research facility.
3.0 Responsibilities:
3.1. Principal Investigator (PI):
Ensures that all personnel involved in handling streptozotocin are properly trained.
Approves and oversee the experimental protocols involving the use of streptozotocin.
Provides appropriate facilities, equipment, and resources for safe handling and storage of streptozotocin.
3.2. Animal Care and Use Committee (ACUC) or Institutional Animal Ethical Committee (IAEC)
Reviews and approves experimental protocols involving the use of streptozotocin.
Monitors compliance with regulatory guidelines and ethical considerations.
3.3. Research Personnel:
Adhere to the guidelines outlined in this SOP.
Complete training on the safe handling, preparation, and administration of streptozotocin.
Report any adverse events or incidents related to streptozotocin use.
4.0 Personal Protective Equipment (PPE):
4.1. Lab Coat: Wear a lab coat or a dedicated protective gown to prevent direct contact with streptozotocin.
4.2. Disposable Gloves: Wear disposable nitrile gloves when handling streptozotocin to protect against skin contact.
4.3. Safety Glasses: Wear safety glasses or a face shield to protect the eyes from accidental splashes or aerosolization.
5.0 Storage and Handling:
5.1. Storage:
Store streptozotocin in a dedicated, locked cabinet or storage area, away from incompatible substances.
Ensure that the storage area is well-ventilated and protected from temperature extremes.
Clearly label the storage container with the name of the compound, concentration, and date of receipt.
5.2. Handling:
Only trained personnel should handle streptozotocin.
Use a designated area or a biological safety cabinet for weighing and preparation of streptozotocin solutions.
Minimize the potential for aerosol generation during handling.
Avoid skin and eye contact with streptozotocin by wearing appropriate PPE.
6.0 Preparation of Streptozotocin Solutions:
6.1. Work in a designated area or a biological safety cabinet to minimize contamination risks.
6.2. Calculate and measure the required amount of streptozotocin accurately, based on the experimental protocol.
6.3. Dissolve streptozotocin in the appropriate solvent (e.g., sterile saline) following the recommended concentration guidelines.
6.4. Mix the solution thoroughly to ensure complete dissolution.
6.5. Label the container with the concentration, date of preparation, and any other relevant information.
7.0 Administration of Streptozotocin to Rodents:
7.1. Follow the approved experimental protocol for the administration of streptozotocin.
7.2. Administer streptozotocin via the approved route (e.g., intraperitoneal or intravenous).
7.3. Adhere to the recommended dosage and timing specified in the experimental protocol.
7.4. Monitor the animals closely during and after administration for any signs of distress, adverse reactions, or complications.
8.0 Waste Disposal:
8.1. Collect all waste, including empty containers, gloves, and other materials contaminated with streptozotocin, in designated biohazard waste containers.
8.2. Dispose of the waste following institutional guidelines and applicable regulations.
9.0 Spill Management:
9.1. In the event of a spill, alert others in the area and restrict access to the spill site.
9.2. Wear appropriate PPE, such as gloves and a lab coat, during the cleanup.
9.3. Absorb the spill with suitable absorbent material and dispose of it as hazardous waste.
9.4. Thoroughly clean the affected area with an appropriate disinfectant.
10.0 Documentation:
Maintain accurate records of streptozotocin usage, including the date of receipt, preparation, administration, dosage, and any adverse events or incidents that occur during the experiment.
11.0 Training:
Ensure that all personnel involved in handling streptozotocin receive comprehensive training on this SOP, including safe handling practices, PPE usage, waste disposal, and emergency procedures.
12.0 References:
12.0 Guidelines on Use of Streptozotocin in Rodents
Include relevant references to guidelines, regulations, or published literature pertaining to the use of streptozotocin in rodents.
13.0 Revision History:
Maintain a log of revisions made to this SOP, including the date and description of each change.
Note: This SOP serves as a general guideline. It is essential to adapt it to your specific research facility's protocols, guidelines, and local regulations. Consult with your institution's animal care and use committee and biosafety officer for further guidance.
