Lateral flow strip
Jun 30,  · A typical lateral flow test strip (presented in Figure 2) consists of overlapping membranes that are mounted on a backing card for better stability and handling. As shown in Figure 3, the sample is applied at one end of the strip, Cited by: The most commonly known type of lateral flow rapid test strip is the pregnancy test. LFDs typically contains a control line to confirm the test is working properly, along with one or more target or test lines. They are designed to incorporate intuitive user protocols and require minimal training to survival5x5.com: Abingdon Health. Strip Test (Lateral flow device) The most commonly used immuno- or antibody-based test for GMO detection is the strip test (also called a lateral flow device or dipstick). Strip tests are thin strips comprised of a nitrocellulose membrane covered by a sample pad on one end and a .

Lateral flow tests[1] also known as lateral flow immunochromatographic assaysare simple cellulose-based devices intended to lateral flow strip the presence or absence of a target analyte in liquid sample matrix without the need for specialized and costly equipment, though many lab-based applications exist that are supported by reading equipment. A widely spread and well known application is the home pregnancy test. The technology is based on a series of capillary beds, such as pieces of porous paper, [3] microstructured polymer, [4] [5] or sintered polymer. The first element the sample pad acts as road rules strip down to nothing sponge and holds an excess of sample fluid. Once soaked, the fluid migrates to the second element conjugate pad in which the manufacturer has stored the so-called conjugate, a dried format of bio-active particles see below in a salt-sugar matrix that contains everything to guarantee an optimized chemical reaction between the target molecule e. While the sample fluid dissolves the salt-sugar matrix, it also dissolves the particles, and in lateral flow strip combined transport action, the lateral flow strip and conjugate mix while flowing through the porous structure. In this way, the analyte binds to the particles while migrating further through the third capillary bed.
