How To Use an Extraction Tube For Antigen Detection?

Posted by anna on March 14, 2022 

The first step in performing an extraction tube for antigen detection is to prepare the specimen. Before performing this test, it is important to properly prepare the samples. The Nasal Swab should be inserted in the bottom of the Extraction Tube. It is essential to rotate it three times against the bottom of the tube. Once this step is complete, the swab should be removed from the sample and disposed of in the biohazard waste stream.

The samples must be stored at 2 to 8 degrees Celsius for at least two days. For longer storage, samples should be kept at -20 degrees Celsius. For long-term storage, they should be stored at -70 degC. After preparation, swabs must be placed in the extraction tube and rolled 5 times. The swab must be held firmly against the bottom of the tube to avoid spilling liquid.

To obtain the best results, the Extraction Tube should be placed into the sample well of the Cartridge. The Sample must be held in place in the tube to minimize spillage. After addition of the samples, the Analyzer should begin the analysis. After 30 minutes, the display will transition to the 'Analysis in Progress' screen. A result will be displayed within one hour. During the process, it is important not to move the cartridge from one place to another. Otherwise, a false positive result may occur.

The Extraction Tube contains colloidal gold-labeled chicken IgY. The goat anti-chicken IgY antibody captures the IgY antibodies. The control line shows whether the liquid flow is appropriate. If there is no colored band on the control line, there is insufficient sample volume. Using the extraction tube for antigen detection, the nasal swabs should be inserted into the sampling tube. The sample should be held firmly against the bottom of the extraction tube to prevent the sample from spilling.

The sample must be stored at 2-8 degC for two days. The sample should be frozen for 3 months. The sample must be kept at -20degC for long-term storage. In case the specimens are processed, the results should be read in 15-30 minutes. In the meantime, the samples should be kept dry at room temperature. An extraction tube should be prepared for the antigen detection. Once the samples are processed, the results will be presented in the form of two colored lines: a control (C) line and a test (T) line.

Once the samples have been prepared, the samples should be stored at 2-8 degC for two days. During the three-month storage period, the sample should be kept at -20degC. For long-term storage, the sample must be stored at -70degC. Repeated freezing and thawing cycles can cause incorrect or invalid results. Hence, it is important to follow the instructions carefully.

How to Prepare an Extraction Tube for a Lateral Flow Assay?

The extraction tube for a lateral flow assay is a syringe that contains the sample to be tested. This sample is then placed in the syringe and rotated in the buffer solution six to ten times. It should be allowed to stand in the syringe for about 1 minute before being removed. Once the syringe has cooled, the swab should be replaced with a new one and the tip should be firmly squeezed to remove it. The sample swab must be disposed of in a safe manner.

Before beginning the lateral flow assay, it is important to be prepared with all the necessary supplies. The swab should be used to collect mucus. It is important to put an alcohol-based hand rub on the swab to avoid spills. A cotton swab should also be used for the lateral-flow assay. Lastly, an extraction buffer bottle should be removed from the swab before beginning the test.

The extraction buffer bottle should contain an enzymatic assay buffer. The syringe should be swabbed with an alcohol-based hand rub before placing it in the syringe. After the swab has been inserted into the syringe, it should be blown out of excess mucus with a tissue paper and an alcohol-based swab. After the sample is collected, the swab should be attached to the dropper tip of the tube. Then, the extraction buffer should be carefully mixed and the four drops of liquid should be placed in the sample well. Air bubbles should be watched during the procedure to avoid causing errors.

To prepare the samples for a lateral flow assay, a swab with a fabric tip should be placed in the lateral flow assay tube. After the swab is placed in the tube, it should be rotated around the swab several times. After completing the assay, the swab should be removed from the extraction tube. Finally, the extraction buffer bottle should be securely screwed to prevent air from leaking out.

The lateral flow assay is a point of care diagnostic test that is easy to perform and can be performed by patients and trained lay users. The test is quick and easy to perform, and the sample can be obtained within a few hours. It is a useful tool for detecting pathogens and biomarkers in human and animal samples. It is also widely used in environmental and food testing. The extraction tube for lateral flow assay should be clean and free from debris or other objects that might contaminate the sample.

To perform the lateral flow assay, make sure you have everything that you need. The swab should be inserted into one nostril and the fluid should be blown out using a soft fabric swab. The swab should be cleaned with an alcohol-based hand rub. Then, place the swab in the bottom of the extraction tube. Then, hold the swab against the edge of the tube for 10 seconds.
