{% endstepper %}

## Advanced Features

### Lineage Tracking and Cell Line Relationships

Understand the complete history and relationships between cell lines, batches, and derivatives.

Cell Line Management automatically tracks relationships including:

* **Parent-child relationships**: Which cell lines or batches spawned which derivatives
* **Passage hierarchy**: Complete passage numbering and progression
* **Batch genealogy**: Visual or detailed views of batch creation timeline
* **Derivative tracking**: Records of modified or selected cell line variants

{% hint style="info" %}
Use lineage tracking to ensure experimental reproducibility by comparing results across passages and identifying when cell line characteristics might change with extended passage.
{% endhint %}

### Batch Certification and Quality Control

Implement comprehensive QC programs with results tracking and acceptance criteria.

{% stepper %}

* Mycoplasma testing (PCR, culture-based)
* Sterility testing results
* Endotoxin levels (if applicable)
* Karyotype or STR authentication results
  {% endstep %}

{% step %}
The system **compares results against criteria** and flags batches that fail acceptance, preventing use of non-conforming material in downstream experiments
{% endstep %}
{% endstepper %}

### CRM Integration for Commercial Operations

Connect inventory management with customer relationship management for seamless business operations.

{% hint style="info" %}

## Troubleshooting

### Issue: Unable to Check Out Vials from Storage

**Symptoms**: Vials appear locked or the check-out button is unavailable for storage items that should be available.

**Solution:**

{% stepper %}
{% step %}
Verify your **user permissions** include:

* Read access to the storage location
* Check-out/removal permissions for inventory items
* Use permission for the specific cell line or batch
  {% endstep %}

{% step %}
Check the **vial status**:

* Ensure the vial is marked as "in storage" or "available"
* Verify it hasn't already been checked out by another user
* Confirm the vial hasn't been marked as expired or discarded
  {% endstep %}

{% step %}
Review the **storage location configuration**:

* Ensure the storage location is active and properly configured
* Verify the freezer or storage system is marked as operational
* Check that coordinate information is complete
  {% endstep %}

{% step %}
If issues persist, contact your **system administrator** to verify role assignments and permission settings
{% endstep %}
{% endstepper %}

### Issue: Batch Fails QC Acceptance Criteria

**Symptoms**: A newly created batch is flagged as non-conforming and cannot be used in experiments.

**Solution:**

{% stepper %}
{% step %}
Review the **QC test results** recorded in the batch:

* Verify the values were entered correctly
* Check against the defined acceptance criteria for that cell line
* Identify which specific parameter(s) failed
  {% endstep %}

{% step %}
**Investigate the root cause**:

* Review the culture conditions and protocol used during batch creation
* Check for deviations in passage method or parameters
* Identify any environmental or equipment issues during production
  {% endstep %}

{% step %}
Determine the **appropriate remediation**:

* Attempt another passage or thaw if the batch is salvageable
* Document the failure in the batch record for traceability
* Request retest or re-certification if appropriate
* Discard if non-viable or contaminated
  {% endstep %}

{% step %}
**Update protocols** if needed:

* Modify culture conditions if systematic issues are identified
* Retrain personnel on protocol execution
* Document any approved deviations or improvements
  {% endstep %}
  {% endstepper %}

### Issue: Vial Location Information is Incomplete

**Symptoms**: Vials are in storage but their coordinate information is missing or unclear, making retrieval difficult.

**Solution:**

{% stepper %}
{% step %}
**Locate the vial** physically in the storage system using available information (freezer name, approximate location, or vial ID/barcode)
{% endstep %}

{% step %}
**Update the vial record** with correct location coordinates:

* Rack or shelf position
* Drawer or compartment number
* Tube row and column (for organized tube racks)
* Specific well location (for organized storage)
  {% endstep %}

{% step %}
Implement **consistent labeling practices**:

* Ensure all vials are labeled with barcodes or clear identifiers
* Use a standardized coordinate system across all freezers
* Train personnel on proper location recording during initial storage
  {% endstep %}

{% step %}
**Prevent future issues** by:

* Requiring coordinate information before vials can be marked as "in storage"
* Conducting periodic inventory audits
* Using barcode scanning for location verification
  {% endstep %}
  {% endstepper %}

### Issue: Cell Line Lineage is Unclear or Incorrect

**Symptoms**: The batch or cell line lineage history is missing or doesn't accurately represent the actual progression.

**Solution:**

{% stepper %}
{% step %}
**Review the cell line records** to trace the history:

* Identify all batches created from the parent cell line
* Check passage numbers for sequence and logic
* Look for gaps in the documented progression
  {% endstep %}

{% step %}
**Correct the parent-child relationships**:

* Re-assign parent cell line or batch information if incorrect
* Update passage numbers to create logical sequence
* Document any historical batches or passages that weren't previously recorded
  {% endstep %}

{% step %}
**Add missing historical documentation**:

* Create batch records for historical passages (use actual creation dates)
* Document any lost or missing passage information with notes
* Indicate which information is reconstructed from memory or records
  {% endstep %}

{% step %}
Use this corrected history going forward to maintain accurate lineage tracking. Consider implementing procedures to prevent future gaps in documentation.
