ImmunoTek™ DAB Stable Liquid Substrate 50X Concentrate, 0.0694mM Staining System for HRPO||DAB is widely used for both immunoblotting and immunohistochemical staining techniques. It produces an insoluble end product that is brown in color and insoluble in alcohol. It is supplied as 50X concentrate.||DAB is the most common reagent employed for the immunohistochemical detection of horseradish peroxidase (HRP) labeled probes. DAB powder from different sources may show great variability with respect to purity. Histochemical grade material should be pale tan with no purple hue. The purple material is a DAB oxidation product that binds avidly to heme proteins such as myoglobin, hemoglobin and particularly, catalase. Therefore purple by-products should be avoided for histochemical uses.||United States Biological provides a stable DAB concentrate manufactured from carefully selected reagents. When diluted in appropriate buffers with added hydrogen peroxide, the resulting solution provides excellent results with most immunohistochemical and blotting procedures.||Note: DAB is a suspected carcinogen.||Color (Light tan to brown):|Passes||Stability (4°C and RT):|Passes||Storage and Stability:|May be stored at 4°C. For long-term storage, aliquot and store at 4°C. Do not freeze. Aliquots are stable for 12 months after receipt.||Related Products:|Tris HCl Buffer is supplied separately (Cat# D1000-05).In the presence of HRP and hydrogen peroxide, DAB is oxidized to an insoluble brown polymer easily recognized by light microscopy. The polymer is insoluble in most organic solvents allowing the use of xylene based mounting medium. Similar color is obtained on blotting matrices.||Features:|• Exhibits low background levels|• Safe to use - no weighing of hazardous powders|• Save preparation time - use right out of the bottle|• Ultra-low sensitivity|• Minimal lot-to-lot variation 2018年8月，蚂蚁淘成为UnitedStatesBiological（简称USBio）代理商，UnitedStatesBiological也简称为USBiological。 欢迎广大客户咨询订货，在线QQ：3507623898 4000-520-616 最主要的一抗产品： 144747-FITC Anti-IL-6(BCellstimulatoryfactor2)(FITC) Pab rabbit human IgG Hu FITC $592 IL6 WB 100ul 144764-FITC Anti-Interferongamma(IFN-gamma)(FITC) Pab rabbit rat IgG Rt FITC $592 IFNG E,IHC,IP,N,WB 100ul 144739-FITC Anti-IL-3(Hematopoieticgrowthfactor,Mastcellgrowthfactor)(FITC) Pab rabbit human IgG Hu FITC $592 IL3 E,IHC,IP,N,WB 100ul 144964-FITC Anti-NFKB1(KBF1,NF-kappaB,NFkappaB,NF-kB1,NFKB-p50,EBP-1,p50,p105,TRANSCRIPTIONFACTORNFKB1,DNA-bindingfactorKBF1,NFKBp50,INCLUDED,NFKBp105,INCLUDED,NuclearfactorofkappalightpolypeptidegeneenhancerinBCells1)(FITC) Pab rabbit human IgG Hu,Mo,Rt FITC $628 NFKB1 WB 100ul 303092-FITC Anti-ACE(ACE1,ACET,ACE_HUMAN,ACE1,AngiotensinConvertingEnzymeSomaticIsoform,AngiotensinConvertingEnzymeTestisSpecificIsoform,AngiotensinIConvertingEnzyme,AngiotensinIConvertingEnzyme1,AngiotensinIConvertingEnzymePeptidylDipeptidaseA1,Angiotensin-convertingEnzyme,Carboxycathepsin,CD143,CD143,CD143Antigen,DCP1,DCP,DCP1,DipeptidylCarboxypeptidase1,DipeptidylCarboxypeptidaseI,KininaseII,MVCD3,PeptidaseP,PeptidylDipeptidaseA,SolubleForm,TesticularECA)(FITC) Pab rabbit human IgG Hu,Mo,Rt FITC $592 IHC,WB 100ul 145142-FITC Anti-SCF(Mastcellgrowthfactor)(FITC) Pab rabbit human IgG Hu FITC $592 KITLG E,WB 100ul 145147-FITC Anti-SDHA(FlavoproteinsubunitofcomplexII)(FITC) Pab rabbit human IgG Hu,Mo,Rt FITC $628 SDHA IHC,WB 100ul 145286-FITC Anti-TNC(Hxb,Hexabrachion,Tenascin-C,TN-C,TN,CYTOTACTIN,hexabrachion(tenascinC,cytotactin),hexabrachion(tenascin),MGC167029)(FITC) Pab rabbit human IgG Hu,Mo,Rt FITC $628 TNC IHC,WB 100ul 303394-FITC Anti-Interleukin1Beta(IL1beta,Catabolin,H1,Hematopoietin1,IFNbetaInducingFactor,IL1,IL1beta,IL1B,IL-1beta,IL1Beta,IL1B,IL1B_HUMAN,IL1F2,Interleukin1betaPrecursor,Interleukin-1beta,LAF,OAF,OsteoclastActivatingFactor,Preinterleukin1beta,Preinterleukinbeta,ProInterleukin1beta)(FITC) Pab rabbit rat IgG Rt FITC $592 E,WB 100ul 303592-FITC Anti-SerumAmyloidP(9.5Salpha1Glycoprotein,9.5Salpha-1-glycoprotein,AmyloidPComponentSerum,APCS,PentaxinRelated,Pentraxin2,PTX2,PTX2,SAMP_HUMAN,SAP,SerumAmyloidPComponent,SerumAmyloidP-component(1-203))(FITC) Pab rabbit rat IgG Rt FITC $592 IHC,WB 100ul 144120-HRP Anti-Actin(Gamma-actin)(HRP) Pab rabbit human IgG Hu,Mo,Rt HRP $628 ACTG1 IHC,WB 100ul 144129-HRP Anti-ADAMTS2(ProcollagenIN-proteinase)(HRP) Pab rabbit human IgG Hu,Rt HRP $628 ADAMTS2 IHC,WB 100ul 144160-HRP Anti-ANGPTL3(ANG-5,ANGPT5,Angiopoietin-5)(HRP) Pab rabbit human IgG Hu,Mo,Rt HRP $628 ANGPTL3 WB 100ul 144183-HRP Anti-ApoptosisregulatorBcl-2(HRP) Pab rabbit human IgG Hu HRP $592 BCL2 E,IP,N,WB 100ul 144190-HRP Anti-AQP3(Aquaglyceroporin-3)(HRP) Pab rabbit human IgG Hu,Mo,Rt HRP $628 AQP3 IC,IHC,WB 100ul
