Kev ua lag luam hloov pauv muaj ntau lub npe thoob ntiaj teb thiab hauv tsev, muab ntau yam khoom xws li nitrocellulose (NC) daim nyias nyias, polyvinylidene fluoride (PVDF) daim nyias nyias, thiab nylon daim nyias nyias kom tau raws li cov kev xav tau ntawm ntau hom kev sim tshuaj lom neeg.
In the nitrocellulose membrane field, representative brands include BeyoGold™, whose product series offers multiple pore sizes such as 0.1μm, 0.22μm, and 0.45μm, featuring high protein binding capacity (>30-50ug/cm²) thiab qis tom qab. Cov khoom tsim muaj xws li qhov ntau thiab tsawg ua ntej txiav (piv txwv li, 6.5 × 8.5cm, 8.5 × 13cm) thiab yob (33cm × 3m), sib xws nrog ntau yam kev tshawb nrhiav xws li chemiluminescence, colorimetry, thiab fluorescence.
Hauv kev lag luam PVDF membrane, cov npe loj suav nrog Millipore thiab PALL. Piv txwv li, PALL's BSP0161 PVDF hloov pauv daim nyias nyias muaj 0.2μm pore loj tsim, nthuav tawm cov tshuaj lom neeg ruaj khov zoo, lub zog txhua yam, thiab muaj peev xwm ua kom muaj protein ntau (txuas muaj peev xwm txog 100-200ug / cm²). Millipore muaj ntau yam khoom xws li Immobilon®-P (0.45μm) thiab Immobilon®-PSQ (0.2μm), haum rau kev tshawb nrhiav cov proteins ntawm qhov sib txawv molecular hnyav.
