Sample Collection and Shipping


To submit cells: 

  • The Client should send one cryovial (or other screw-top tube) of each sample with a minimum of 1x10cells/vial. 
  • Cells may be in the form of a pellet or in growth media, freeze media or phosphate-buffered saline. 
  • NOTE: cells are preferred, but if DNA is high quality, it may be submitted. 

To submit tissue/solid tumor samples: 

  • The Client should send a 1.5 mL snap top or screw top tube of each sample with a minimum of 30 mg of tissue (2-3mm size fragment or larger). 

To submit DNA: 

  • DNA must be submitted as high quality extracted DNA (crude lysate extractions are not suitable for STR analysis) 
  • DNA needs to be submitted with a minimum of 150ng of DNA in a minimum volume of 15 μl. 
  • Optimal concentrations submitted are preferred at >20 ng/μl. DNA concentration must be at least 10 ng/μl. 
  • NOTE: Frozen cell cultures or tissue are preferred. Submission of cells allows extraction of the DNA in our facility for optimal DNA quality and test results. 
  • Send DNA in a tube with screw top cap if available. If a snap top tube is used, secure the top with Parafilm™ before shipping. DNA samples can be shipped at room temperature by regular ground shipment. During hot weather, ship samples overnight with an ice pack to prevent exposure to excessive heat.

Cell Line Authentication Guide

Biotech & Pharma

Cell line misidentification or contamination is common in R&D labs worldwide, costing time, money, and significant setback in program development. This guide discusses the impact of cell line authentication (CLA) in research labs, when to conduct testing, a sample authentication plan, and more.


Cell Line Authentication Guide


Cell line authentication (CLA) provides researchers with the validation they need to confidently move their research forward. This guide explores the impact of CLA in research labs, compliance with NIH Notification #NOT-OD-16-011, and more.
