Top - Why should I collect and store DNA?
|
|
| Top - Why do I have to wear gloves? |
|
The FTA ® paper is very sensitive and you can contaminate the sample area. We do not supply gloves with our kits because of the added expense and extra packaging requirements. You can purchase a full box of latex or vinyl exam gloves from your local drug store for very little money. New gloves should be used for each new sample taken. Even while wearing gloves, do not touch the sample area on the FTA ® Card. You should also avoid sneezing, spitting, coughing, or breathing on the sample paper. |
| Top - How many samples can you collect with the GenoFam™ Kits? |
|
The GenoFam Plus 1™ Kit collects one DNA sample per person. |
| Top - Can your kits be used for medical diagnosis? |
|
No, the GenoFam™ kit and the FTA ® technology employed in the kit is not classified for use by the FDA as a "medical device." Our kits can be used for identification and other purposes not used for medical diagnostics. Medical devices are regulated by the FDA. |
| Top - Why can't your kit be used on infants? |
|
Samples are collected using a foam-tipped applicator. The tip of the applicator could cause your infant to choke. |
| Top - Can children use the kits? |
| Yes, adults should take samples for children. Children may choke on the foam-tipped applicator or use improper collection technique if left unsupervised. |
| Top - What is the special paper used to store the DNA and how does it work? |
|
The special paper utilized is called FTA ® and is patented by Whatman Biosciences. FTA stands for "Flinders Technical Associates" after is place of conception in Australia. In general, cells from the cheeks and gums are deposited onto the sample paper. Nontoxic chemicals embedded in the paper break open the cellular contents exposing the DNA. DNA is then extracted onto the paper. Special chemicals help to protect the DNA in addition to deactivating most harmful bacteria and viruses. The paper card has a flap that further protects the DNA sample from being touched. When sealed in the specially designed 7-layer envelop, the DNA is protected from light, air, and the physical environment that would otherwise degrade it over time. The sample can be directly analyzed. A small 1.2- 2mm circular punch is taken from the FTA ® paper and placed into a micro-centrifuge tube (a very small plastic test tube). Buffer, enzymes, and DNA building blocks are added to the sample. The small amount of sample DNA is then increase by a process called Polymerase Chain Reaction (PCR). Specific gene regions of interest are duplicated until enough DNA is available to be directly analyzed by various laboratory methods. |
| Top - Are the chemicals embedded in the paper harmful? |
|
No, the chemicals embedded in the paper are nontoxic, but we do not recommend that you touch or place the paper into your mouth. The FTA ® Card is very sensitive and you can easily contaminate the paper. |
| Top - Can the DNA sample be sent through the mail? |
|
Yes, once the DNA is extracted and sealed within the protective envelope it can be sent to the laboratory or to anyone else via normal mail service. Harmful viruses and bacteria are left inactive by chemicals embedded in the paper and the sample is not considered a biohazard. |
|
No, although FTA ® technology is a highly effective storage method, future DNA recovery is dependent upon many factors including proper sample collection, proper storage conditions, etc... No DNA storage method is 100% foolproof. |
| Top - How long does the DNA last? |
|
So far, stability studies have shown DNA to remain stable for twelve years on FTA ® Cards stored at room temperature . It is estimated that the DNA will last for decades. |
