Yes. Preliminary tests peformed on evidence can detect the presence of blood and semen. These areas can then be targeted for DNA analysis.

Two types of tests are commonly used to detect HIV infection. The most commonly used initial test is an enzyme immune assay (EIA) or the enzyme-linked immunosorbent assay (ELISA). If EIA test results show a reaction, the test is repeated on the same blood sample. If the sample is repeatedly reactive, the results are "confirmed" using a second test such as the Western blot.

Yes. The Model 935 allows modification of the isotopic radiation lines in its library. One can very easily enable or disable a particular energy line in order to optimize results. This is helpful when two or more lines are very close. In this case, however, you would not need to modify the lines. Good results can be obtained without altering the standard library since there is ample seperation between all major lines (Cs-137: 662 and 32 keV; Am-241: 59.5 and 26 keV). See similar questions...

Blood in ejaculated semen (hemospermia) is relatively uncommon and rarely serious. In most cases, the cause can't be determined, and the problem goes away without treatment. However, known causes of blood in semen include inflammation, infection and blockage or injury to the prostate gland or seminal vesicles. Also, following a prostate biopsy, it is common to have blood-tinged semen for four or five subsequent ejaculations. See similar questions...

We believe that greater industry collaboration is one of the most effective ways to bring about meaningful, lasting change in garment factories. Achieving widespread collaboration is no easy task, however. For one thing, different companies place different levels of importance on monitoring and enforcing labor standards in garment factories. Not everyone takes this as seriously as we do. See similar questions...

Where the levels of hCG are low and the woman has no severe symptoms of ectopic pregnancy, your doctors may make a decision to treat you 'expectantly'. Expectant management is increasingly common. It means that the patient is observed closely and the pregnancy given the opportunity to resolve without treatment, which is possible when hCG levels are low. See similar questions...

Many participants' blood samples will be used for genetic (DNA) testing. Some of the most important questions that may be answered by the Sister Study are about relationships between genes and the chance that a woman will get breast cancer. It is important that you know that any analyses using your blood samples will NEVER include information that would identify you personally. See similar questions...

I have not tested the phone detection of the NDS installation software personally. If you do not know if your homemade adapter works with the NDS software, I recommend you to choose the correct COM port manually or use the original cable supplied in your Nokia Data SuiteTM package in the installation phase. The interface behavior on software level is not my business. I have researched only hardware problems in this case and I have no documentation on the protocol. See similar questions...

This is very much dependent upon the type of garment worn, the nature of the wearer and whether the garment is worn alone or under other clothing. It is generally expected that the garments used for infants are more likely to be out-grown rather than worn out. See similar questions...

I've had several relatives die before their time due to tobacco related illness and I am frustrated daily. See similar questions...

IMPORTANT! Contact your physician for the collection of blood samples for children under 8 years of age. GTL offers this option because it is much faster and easier for you to collect. The procedure involves a small lancet that is used to lightly pierce a finger (most don't even feel it). A small drop of blood is then transferred to a collection card - that's it. There is no additional cost if you choose buccal (cheek) swab testing. Buccal is the "Cheek Swab" Test. See similar questions...

No. DNA purified with the PAXgene™ Blood DNA system is free of detectable RNA contamination. In contrast to commercial salting out methods, additional RNase digestion steps are not necessary. See similar questions...

DNA purified using the PAXgene™ Blood DNA System should be dissolved in Buffer BG4 and stored at 2-8?C. For long-term storage, DNA can be stored at -20?C but multiple freezing and thawing cycles should be avoided. Yes. After dissolving the nuclei pellet in digestion buffer, Buffer BG3 (step 7), samples can be stored up to 7 days at 2-8?C or for one day at room temperature (18-25?C). The protocol can also be interrupted after adding isopropanol (step 10). See similar questions...

Frozen blood can be used, but must be shipped frozen to OptiGen. Frozen semen can be used for most tests. Please read the details for use and shipping at the link "Instructions and Information". See similar questions...

GCAT has offered two hands-on workshops so far, though no others are planned at this time. You should check with Cold Spring Harbor's Dolan DNA Learning Center. There have been two MAGIC Tool workshops as well. See similar questions...

No, a blood collection set does not have to be used with the PAXgene™ Blood DNA Tube. Further information on phlebotomy technique with the PAXgene™ Blood DNA Tube can be found in the product circular. Are there any special considerations for phlebotomy when using the PAXgene™ Blood DNA Tube (blood collection set, discard tube, positioning of the tube, issues with short draws etc.). See similar questions...

See "Sample Storage and Archiving" section for specific storage temperature and time information. Individual laboratories should validate shipping procedures. See similar questions...

Blood samples can be stored at 15-25?C for up to 14 days or at 2-8?C for up to 28 days. For longer-term storage, freezing the samples at -70?C or -80?C is recommended. See similar questions...

The amount of Buffer BG1 (lysis buffer) prefilled in the processing tubes, and all the other buffer volumes are optimized for use with blood from one PAXgene™ Blood DNA Tube. See similar questions...

Answer: Yes. Using Crest Mode harmonics may be detected (refer to user's guide for more information). See similar questions...
