- When ordering stock products, simply contact UTAK by phone, fax or email to place your order. A valid purchase order or credit card is necessary to process the order.
- When ordering custom products, you must first sign a valid quotation to confirm the pricing and product specifications.
- Lyophilized controls should be stored at 2-8°C. After reconstitution, the liquid control material should be stored at 2-8°C.
- Frozen controls should be stored at -10°C. After thawing, the liquid control material should be stored at 2-8°C.
- Lyophilized controls have a shelf life of 24-36 months.
- Frozen controls have a shelf life of 12-18 months.
- After reconstitution or thawing most analytes will remain stable for 25-30 days if the control material is stored and handled properly
- Preservatives and additives can cause significant matrix effects, particularly with immunoassay test methods, which is why UTAK offers controls manufactured in 100% human matrices.
- NEVER vortex a whole blood control after reconstitution – the whole blood will foam and the performance of the control will suffer.
- After reconstitution, allow a whole blood control to equilibrate for one hour at room temperature.
- Controls containing Delta-9-THC must be packaged in the frozen form as the lyophilization process triggers degradation.
- Silanized amber glass vials should always be used to protect the stability of Delta-9-THC in any matrix.
