## 1. Introduction

Consistent laboratory practices ensure reliable, reproducible peptide research. This guide covers essential best practices for all peptide work.

## 2. Documentation

Maintain a peptide log with:

* Date received
* Date opened
* Reconstitution details
* Experimental notes
* Storage history

## 3. Storage

Standard: -20°C, desiccated, light-protected. Monitor temperature regularly. Record temperature in log.

## 4. Sample Management

Use consistent labeling system. Track location in lab. Monitor expiry dates. Dispose properly when expired.

## 5. Quality Control

Verify each batch upon receipt. Check COA against product. Document any discrepancies.

## 6. Record Keeping

Keep records for minimum 3 years. Include batch numbers in all publications. Digital backup of all documentation.

## 7. Traceability

Every sample should be traceable to:

* Original batch number
* COA
* Date of receipt
* Storage conditions

## 8. Audit Preparation

Maintain organized documentation:

* COAs in chronological order
* Receipt logs
* Temperature records
* Deviation reports

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.rplpeptides.com/docs/guides/peptide-laboratory-best-practices.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
