In the Tris Glycine buffer system, the molecular weight range is 10-180 kDa; In the Bis Tris (MOPS) buffer system, the molecular weight range is 9-170 kDa. In the HEPES buffer system, the molecular weight range is 10-170 kDa. In the SDS-PAGE (Tris Glycine) experiment, the protein covalently couples with the blue chromophore to form a blue band, and two reference bands have enhancement effects (25 kDa green band and 75 kDa red band, respectively). RealBand pre staining Marker can be used to monitor protein separation during the SDS-PAGE process, verify Western membrane transfer efficiency (PVDF membrane, NC membrane), and determine protein molecular weight. The RealBand pre stained protein marker is stored in the loading buffer and can be used directly. Do not heat, dilute, or add other reducing agents before loading the sample.\n\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003c!-- Specification --\u003e\n\u003cdiv class=\"biofargo-sec\"\u003e\n\u003ch2 class=\"biofargo-h2\"\u003eSpecification\u003c\/h2\u003e\n\n\u003cdiv class=\"biofargo-table-wrap\"\u003e\n\u003ctable class=\"biofargo-table w-640\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth style=\"width:40%\"\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\n\u003ctbody\u003e\n\n\u003ctr\u003e\n\u003ctd\u003eFull name\u003c\/td\u003e\n\u003ctd\u003eRealBand Pre-stained Protein Marker，3 colors，Standard Range，10~180 kDa\u003c\/td\u003e\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\u003ctd\u003eApplications\u003c\/td\u003e\n\u003ctd\u003eSDS-PAGE, WB membrane transfer, molecular weight estimation\u003c\/td\u003e\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\u003ctd\u003eComposition\u003c\/td\u003e\n\u003ctd class=\"center\"\u003e250ul\/4X 250ul\u003c\/td\u003e\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\u003ctd\u003eNumber of Markers\u003c\/td\u003e\n\u003ctd class=\"center\"\u003e10\u003c\/td\u003e\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\u003ctd\u003eSize Range\u003c\/td\u003e\n\u003ctd class=\"center\"\u003e10 to 180 kDa\u003c\/td\u003e\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\u003ctd\u003eMolecular Weight (g\/mol)\u003c\/td\u003e\n\u003ctd\u003e10,15,25,35,45,60,75,100,140,180 kDa (Tris-Glycine)\u003c\/td\u003e\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\u003ctd\u003eStain Type\u003c\/td\u003e\n\u003ctd class=\"center\"\u003e3 colors: Blue, Orange, green\u003c\/td\u003e\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\u003ctd\u003eGel Compatibility\u003c\/td\u003e\n\u003ctd\u003eTris-Glycine Gels; Bis-Tris Gels ; HEPES Gels\u003c\/td\u003e\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\u003ctd\u003eConcentration\u003c\/td\u003e\n\u003ctd class=\"center\"\u003e0.1~0.4 μg\/μl\u003c\/td\u003e\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\u003ctd\u003eApplications\u003c\/td\u003e\n\u003ctd\u003eSDS-PAGE, WB membrane transfer, molecular weight estimation\u003c\/td\u003e\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\u003ctd\u003eComponent\u003c\/td\u003e\n\u003ctd class=\"center\"\u003e250ul\/4X 250ul\u003c\/td\u003e\n\u003c\/tr\u003e\n\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003c!-- Features --\u003e\n\u003cdiv class=\"biofargo-sec\"\u003e\n\u003ch2 class=\"biofargo-h2\"\u003eFeatures\u003c\/h2\u003e\n\u003cul class=\"biofargo-features\"\u003e\n\u003cli\u003eHigh strip resolution, bright colors, easy to observe, long shelf life, and stable properties\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003c!-- Application --\u003e\n\u003cdiv class=\"biofargo-sec\"\u003e\n\u003ch2 class=\"biofargo-h2\"\u003eApplication\u003c\/h2\u003e\n\n\u003cdiv class=\"biofargo-card\" style=\"background:#fff;\"\u003e\n\u003cp style=\"margin:0 0 16px 0;\"\u003e\nThe RealBand Pre-stained Protein Marker contains 10 pre-staining proteins.

contains 10 types of pre stained proteins. In the Tris Glycine buffer system, the molecular weight range is 10-180 kDa; In the Bis Tris (MOPS) buffer system, the molecular weight range is 10-200 kDa. In the HEPES buffer system, the molecular weight range is between 11 and 180 kDa.

In the Tris Glycine buffer system, the molecular weight range is 10-180 kDa; In the Bis Tris (MOPS) buffer system, the molecular weight range is 9-170 kDa. In the HEPES buffer system, the molecular weight range is 10-170 kDa. In the SDS-PAGE (Tris Glycine) experiment, the protein covalently couples with the blue chromophore to form a blue band, with two reference bands having enhancement effects (25 kDa and 75 kDa blue enhancement bands, respectively). RealBand pre staining Marker can be used to monitor protein separation during the SDS-PAGE process, verify Western membrane transfer efficiency (PVDF membrane, NC membrane), and determine protein molecular weight. The RealBand pre stained protein maker is stored in the loading buffer and can be used directly.

In the Tris Glycine buffer system, the molecular weight range is 5-245 kDa; In the Bis Tris (MOPS) buffer system, the molecular weight range is 3.5~235 kDa. In the HEPES buffer system, the molecular weight range is 10-245 kDa. In the SDS-PAGE (Tris Glycine) experiment, proteins covalently couple with blue chromophores to form blue bands. Two reference strips have a strengthening effect (25 kDa green and 75 kDa red strips, respectively). RealBand pre staining Marker can be used to monitor protein separation during the SDS-PAGE process, verify Western membrane transfer efficiency (PVDF membrane, NC membrane), and determine protein molecular weight.

In the HEPES buffer system, the molecular weight range is 10-245 kDa. In the SDS-PAGE (Tris Glycine) experiment, proteins covalently couple with blue chromophores to form blue bands. Two reference strips have a strengthening effect (25 kDa green and 75 kDa red strips, respectively). RealBand pre staining Marker can be used to monitor protein separation during the SDS-PAGE process, verify Western membrane transfer efficiency (PVDF membrane, NC membrane), and determine protein molecular weight.
