Immobilized antibody
WitrynaAntibody sacrificed: as a consequence of harsh elution conditions, the target antibody is destroyed; antibody loss by way of the protocol can be costly. Antibody re-used: immobilization chemistry and mild elution conditions for the target and associated proteins allow the immobilized antibody to be re-equilibrated and re-cycled several … Witryna2 lut 2014 · 26183-D650 has been successfully used for immunofluorescence. DyLight 650 has an excitation/emission of 652/672 nm. HA Synthetic Peptide (Product No. 26184) is available for use in neutralization and control experiments and to competitively elute HA-tagged fusion proteins from immobilized anti-HA affinity resin.
