The QIAGEN® indicating elute micro card has one 25mm sample application area per card with a 40µL sample size per circle. The Indicating FTA™ elute matrix is the same chemistry as FTA™ elute with an indicating dye that changes from purple to white upon application of a colorless sample such as saliva urine buccal cell swabs cultured cells and bacterial cultures. Samples can be collected shipped and stored at room temperature. This eliminates high costs associated with shipping samples on ice and with laboratory freezer storage requirements. It rapidly inactivates organisms including bloodborne pathogens which eliminates the risk of contamination for the individuals handling the sample. This also eliminates classifying samples as biohazards. Sample processing time to isolate DNA is 15 to 30 minutes and eliminates lengthy and multiple step isolation procedure (4 to 16 hours). Sample processing requires a simple hot water elution procedure to isolate DNA. The cost of using a purification kit is avoided. Sample volume requirements are minimal: 12 to 40µL per collection area. This eliminates venous blood samples and large blood volume handling/processing. It further eliminates the need for venipuncture equipment and a medical attendant at the site of collection. Hemoglobin a known PCR inhibitor is bound to the FTA™ elute matrix. DNA is recovered in solution free of PCR inhibitors. 100/Pack. QIAGEN® #: GBS WB120411.
