Test ID: I SOX10 CPT Code: 88342
Expected Turnaround Time
2 days
Stated turn-around-times (TATs) are for clinical use only and subject to change based on biopharma protocol requirements. Final TATs will be specified in the biopharma study contract.
Clinical Information
SOX10 is a transcription factor that plays a crucial role in the development of neural crest cells and is widely used in pathology to identify neural crest-derived tumors. It is particularly valuable in diagnosing melanoma, schwannomas, and peripheral nerve sheath tumors, where its expression helps distinguish these from other neoplasms. SOX10 is also used to assess tumor differentiation, and its presence in certain tumors can aid in determining the prognosis and guiding therapeutic decisions.

Specimen Requirements

Specimen Requirements
  • Fresh Tissues: Fixative should be at a 20:1 fixative to tissue ratio, 10% neutral buffered formalin (NBF) for 6-72 hours (48-72 hours PREFERRED)
  • Formalin-fixed Paraffin Embedded Tissue (FFPE blocks): FFPE Block, Formalin Fixed
  • Unstained slides: 2 slides (3-5 μM) per stain (min 1 slide per stain), Formalin Fixed
Specimen Stability
  • Fresh Tissue Tissues: ≤ 72 Hours
  • Formalin-fixed Paraffin Embedded Tissue (FFPE blocks): Indefinite
  • Unstained slides: Indefinite
Storage Requirements

15°C to 25°C

Shipping Conditions
Ambient
Shipping Recommendations
  • Fresh Tissues: AMBIENT
  • Formalin-fixed Paraffin Embedded Tissue (FFPE blocks) and unstained slides: AMBIENT, Use a refrigerated (NOT FROZEN) gel pack in the shipment to protect from extreme temperatures. Separate gel pack from specimen.
  • Specimens may be transferred to 70% alcohol for transportation purposes after fixation in 10% NBF or B plus.
Specimen Rejection Criteria

Special Considerations
  • Fresh Tissues: Specimens may be fixed in formalin for 24-72 hours by collection sites, then transferred to 70% ethanol and stored at 2-8°C for longer term storage if needed. Samples must be tested 3 months after placing in ethanol.
  • Unstained slides: Positively charged glass slides required to prevent background staining and prevent tissue loss. Slides should be left unbaked.
