Plates intended for quantitative and qualitative solid phase immuno assays (e.g. ELISA) and binding assays. Choice of Surface: PolySorp, with high affinity to molecules of a hydrophobic nature. MediSorp, has a surface chemistry intermediate between PolySorp and MaxiSorp. Provides low background signal with samples containing serum. MaxiSorp, with high affinity to molecules with mixed hydrophilic/hydrophobic domains. MultiSorp, with high affinity to hydrophilic molecules. ? Choice of F, C and U bottoms ? Raised rims on the wells ? Certified binding homogeneity ? Alphanumeric orientation system ? When centrifuging MicroWell Plates use Spacer Plate (Cat. No. 757-11263) as support ? Fit standard equipment ? Size: 128 x 86 mm ? Without lid The manufacture and use of synthetic materials for solid phase immunoassays as covered under EU patent No. 0126392 and US patent No. 4,980,299 is licensed to Nunc A/S.
