How GF2, GL0194 and H5072 Fit in Lateral Flow Strip Structures
Strip stability is rarely decided by one material alone. Sample treatment, conjugate release, NC membrane reaction and absorbent driving force work together. GF2, GL0194 and H5072 should be evaluated in the full strip structure.
GF2: focus on whole blood pretreatment
GF2 is often evaluated for whole blood filtration, plasma release, red cell retention and the sample state before entering downstream membranes.
Do not judge only by filtration speed. Also check whether enough plasma is released, whether the conjugate pad rehydrates consistently, and whether the NC membrane shows matrix background.
GL0194: focus on release and interface compatibility
GL0194 can be evaluated as a glass fiber or conjugate pad candidate, especially for conjugate loading, rewetting, release residue and treatment buffer compatibility.
For weak C/T lines, residual conjugate, dirty background or uneven release, compare GL0194 with candidates such as Ahlstrom 8964 under the same dispensing amount, treatment buffer and drying condition.
H5072: focus on absorbent driving force
The absorbent pad is not only the terminal component. Insufficient driving force may cause incomplete flow, while excessive driving force may shorten reaction time and influence line intensity.
Build a combined validation record across sample pad or blood filter, conjugate pad, NC membrane and absorbent pad to avoid misattributing the root cause.
FAQ
Can GF2, GL0194 and H5072 be discussed together?
Yes. They support different strip positions and are suitable for early screening or troubleshooting as a combined material plan.
Why can absorbent pad influence sensitivity?
Absorbent driving force changes residence time on the NC membrane and indirectly affects line intensity and repeatability.
What should be checked first in whole blood projects?
Start with red cell handling and matrix background, then verify conjugate release and absorbent driving force.
