Western blot Western blot using an antibody that recognizes proteins modified with lipoic acid. The western blot (sometimes called the protein immunoblot) is a widely used analytical technique used to detect specific proteins in a sample of tissue homogenate or extract.It uses gel electrophoresis to separate native proteins by 3-D structure or denatured proteins by the length of the polypeptide.he name western blot was given to the technique by W. Neal Burnette and is a play on the name Southern blot, a technique for DNA detection developed earlier by Edwin Southern.

Northern blot Northern blot. A northern blot is a laboratory method used to detect specific RNA molecules among a mixture of RNA. Northern blotting can be used to analyze a sample of RNA from a particular tissue or cell type in order to measure the RNA expression of particular genes. This method was named for its similarity to the technique known as a Southern blot.

Can we use a simple blood test to detect cancer? Breast cancer could be detected using a blood test, according to reports out today. Scientists at the Australian National University (ANU) are working with counterparts in France to make this form of cancer detection, that is far less invasive and expensive than other tests such as biopsies, a reality.

- A Lyme disease test detects antibodies to the Lyme disease bacteria Borrelia burgdorferi in the blood. Lyme disease bacteria are spread by certain kinds of ticks. Lyme disease can be hard to diagnose because its symptoms are similar to those of many other illnesses. This common and rapid test to identify Lyme disease antibodies is the most sensitive screening test for Lyme disease. 2  Western blot test. 3  This test also identifies Lyme disease antibodies and can confirm the results of an ELISA test.

- The M256A1 kit is a portable, expendable item capable of detecting and identifying hazardous concentrations of chemical agent. It is designed to detect Blister, Blood, and Nerve agents. In the field, this kit was called simply the M256. The M256 kit is used after a chemical alert to determine if it is safe to unmask. The M256A1 kit has replaced the M256 kit. The only difference between the two kits is that the M256A1 kit will detect lower levels of nerve agent.

HIV âsalivaâ test as effective as blood test, study finds HIV ‘saliva’ test as effective as blood test, study finds. A rapid oral test called OraQuick that collects mouth fluids to diagnose HIV is nearly as accurate as traditional blood tests, says a new study from a group out of McGill University. The OraQuick test, which collects oral fluid from the inner gum line, can detect HIV antibodies within 20 minutes. A rapid oral test that collects mouth fluids to diagnose HIV is nearly as accurate as traditional blood tests and could help to curb the global HIV/AIDS epidemic, a new study has found.

What is EquiChekâ¢-SAA? What does EquiChek™ Detect. The EquiChek test detects a protein called Serum Amyloid A (SAA) which circulates in the blood. In a healthy horse SAA is generally very low, but the level of SAA rises significantly when the horse experiences a challenge that causes inflammation such as infection or damage to muscle.

Northern blot Northern blotting involves the use of electrophoresis to separate RNA samples by size, and detection with a hybridization probe complementary to part of or the entire target sequence.ith northern blotting it is possible to observe cellular control over structure and function by determining the particular gene expression rates during differentiation and morphogenesis, as well as in abnormal or diseased conditions.

How Bloodstain Pattern Analysis Works As unpleasant as it is to deal with, when a crime results in bloodshed, the blood left behind functions as evidence for investigators. A bloodstain pattern analyst can't simply glance at drips and smears of blood and immediately tell you the who, what and when of a crime scene.Blood spatter analysis takes time and is just one piece of the puzzle when investigators are putting together the elements of a crime.However, bloodstain pattern analysis can corroborate other evidence and lead investigators to seek additional clues. bloodstain pattern analyst can't simply glance at drips and smears of blood and immediately tell you the who, what and when of a crime scene.

Northern blot | more... Northern blot is a technique used in molecular biology research to study gene expression. It takes its name from its similarity to the Southern blot technique, named for biologist Edwin Southern. The major difference is that RNA, rather than DNA, is analyzed in the northern blot.

Western blot The proteins are then transferred to a membrane (typically nitrocellulose or PVDF), where they are stained with antibodies specific to the target protein. The gel electrophoresis step is included in western blot analysis to resolve the issue of the cross-reactivity of antibodies.he name western blot was given to the technique by W. Neal Burnette and is a play on the name Southern blot, a technique for DNA detection developed earlier by Edwin Southern.

Can HIV Be Detected With a CBC Test? If someone with abnormal CBC results is also at risk for HIV, a doctor will order the HIV ELISA test. This test helps determine if there are HIV antibodies in the patient's blood or urine sample. If the HIV ELISA test is positive, the patient has to have the HIV Western blot test to confirm the positive result.
