Laboratory Handling

On Receipt

Inspect before handling

When an order is received, inspect the external packaging and product before beginning laboratory work.

Check:

• Product name and format
• Packaging condition
• Tamper-evident seals where present
• Batch or lot number
• Storage information
• Available accompanying documentation

Record the batch or lot identifier shown on the product or packaging and compare it with applicable documentation where available. If packaging, seals, identification or documentation appear inconsistent, isolate the product and contact Peptissima before using it for research.

Product Identification & Documentation

Establish traceability from the beginning

Before placing a research material into storage, record sufficient information to maintain traceability throughout its laboratory lifecycle.

This should include, where applicable:

• Product name
• Batch or lot number
• Date received
• Manufacturer or supplier
• Storage requirements
• Storage location
• Available Certificate of Analysis
• Date first opened

Where batch-specific documentation is available, ensure that the product identifier corresponds with the applicable documentation.

Quality & documentation

Storage

Follow product-specific storage requirements

Storage requirements vary according to the material, formulation, packaging and manufacturer specifications. Always follow the storage conditions stated on the product label or within the applicable manufacturer documentation.

Research materials may require controls relating to:

• Temperature
• Light exposure
• Moisture
• Container integrity
• Storage duration

Do not assume that storage requirements for one peptide or product format apply to another.

Temperature Changes

Minimise unnecessary environmental exposure

Laboratory materials stored under refrigerated or frozen conditions should be handled in accordance with the applicable product-specific procedure.

Where appropriate for the material, allowing a sealed container to approach the required handling temperature before opening can reduce condensation within the container.

Avoid unnecessary temperature cycling and repeated removal from controlled storage.

Laboratory Handling

Maintain a controlled working environment

Research materials should be handled using appropriate laboratory procedures and equipment.

Researchers should:

• Work within an appropriately controlled laboratory environment.
• Use suitable personal protective equipment.
• Maintain clean working surfaces and equipment.
• Minimise unnecessary environmental exposure.
• Prevent cross-contamination between materials.
• Keep containers securely closed when not actively in use.
• Follow applicable institutional laboratory procedures.

Product-specific handling information should always take precedence over general guidance.

Material Integrity

Protect the research material

Peptide and other research materials may be affected by environmental and physical conditions.

Depending on the specific product, factors affecting material integrity can include:

• Temperature variation
• Moisture
• Light exposure
• Repeated temperature cycling
• Contamination
• Inappropriate handling
• Compromised packaging

Where the condition or integrity of a product is uncertain, do not assume that it remains suitable for research.

Laboratory Records

Maintain clear records

Good record keeping is the basis of traceability and reproducibility.

Maintain an appropriate laboratory record containing:

• Receipt date — when the material entered the laboratory.
• Product and batch — product identification and applicable batch or lot number.
• Storage location — where and under what conditions the material is maintained.
• Documentation — relevant Certificate of Analysis or supporting manufacturer documentation.
• Opening date — when the original product packaging was first opened.
• Laboratory use — appropriate internal records relating to use of the research material.

If Something Doesn't Look Right

Stop and check

Do not proceed with research where:

• Packaging has been compromised.
• A seal appears damaged.
• Product identification is unclear.
• Batch information does not correspond with available documentation.
• Required storage conditions may have been compromised.
• The material's condition raises concerns.

Retain the product and packaging and contact Peptissima with the relevant order and batch information.

Product-Specific Information

General guidance is not a substitute

General laboratory guidance cannot account for every peptide, formulation or product format.

Before handling a product, researchers should review:

• Product-specific information
• Product labelling
• Available manufacturer documentation
• Applicable Certificate of Analysis
• Their institution's laboratory procedures

Where these differ from general information presented by Peptissima, the appropriate product-specific or institutional requirements should be followed.
