vWF – von Willebrand Factor Deficient or Depleted Plasma
Affinity’s vWF – von Willebrand Factor Deficient or Depleted Plasma is manufactured from pooled normal human plasma depleted of von Willebrand Factor using antibodies directed to vWF. Only the highest quality citrated plasma is used as starting material. Our Frozen Deficient or Depleted Plasma products are typically buffered with the addition of HEPES to 20mM final concentration and our Lyophilized Deficient Plasma products are typically buffered with the addition of HEPES to 50mM final concentration.
All vWF – von Willebrand Factor Deficient or Depleted Plasma from Affinity Biologicals are for Research Use Only and must not be used for diagnostic applications.

Abnormal Control Plasma – Lyophilized
Abormal Control Plasma – Lyophilized
The VisuCon-L Abnormal Control Plasma – Lyophilized is an assayed control plasma intended for use in the quality control of coagulation assays in the borderline pathological range. This control plasma may be used to monitor the performance of coagulation assays for the following parameters: fibrinogen (Clauss Method), coagulation factors II, V, VII, VIII, IX, X, XI, XII, antithrombin activity, Protein C activity, and Protein S activity.
This Abnormal Control Plasma – Lyophilized may be used with mechanical and photo-optical coagulation instruments in conjunction with appropriate commercial reagents. Good laboratory practice requires that assays be calibrated over the relevant range and that controls be performed regularly to confirm assay calibration. This plasma is citrated human Pooled Normal Plasma – PNP collected from a minimum of 20 donors, buffered with 0.05M HEPES buffer, as well as stabilizing agents, dispensed and lyophilized.
VisuCon-L Abnormal Control Plasma – Lyophilized is cleared for in vitro Diagnostic use by FDA and CE marked. Available for sale in the United States and select European countries.
- Box containing 10 x 1 mL vials of lyophilized plasma, Prod. # LYABP01
The results obtained with the VisuCon-L Abnormal Control Plasma – Lyophilized will be subject to the limitations of the assay system including types of reagents and instrumentation.
Preparation/Handling:
Reconstitute each vial with 1 ml reagent grade water. Swirl gently and let stand for 15 minutes. Swirl gently once more before use.
Storage and Stability:
Vials are stable until the expiration date stated on the vial when stored at 2 – 8°C. Once reconstituted, the plasma is stable for 24 hours on-board (15 – 22°C) or at 2 – 8°C in original vial. Gently mix vial of plasma if left for more than 2 hours without use. Reconstituted material should be discarded after use and not be refrozen.
Assay Procedure:
After reconstituting the VisuCon-L Abnormal Control Plasma – Lyophilized, use on coagulation instrument or assay system with corresponding reagents in accordance with established coagulation assay procedures. If appropriate control values are not obtained, assess the components of the assay system including reagents, substrate plasmas, calibrator plasma or instrumentation to try and identify potential sources of error.
