It doesn't necessarily relate directly to Baker's story, but it may be intended to suggest a possible further affinity between Baker and Jumbo.
A sample of the IgG fraction was further affinity purified using a Flag peptide-conjugated column prepared using the Sulfolink immobilization kit for peptides (Pierce).
Its superior specificity makes it an ideal candidate for further affinity maturation.
Further, affinity imaging offers a means to localize specific molecules on cells, such as cell adhesion proteins and antibiotic binding sites [11, 44].
Briefly, plasminogen depleted human fibrinogen (Calbiochem, Meudon, France) was further affinity purified on a protein G column (HiTrap protein G; Amersham Biosciences, Orsay, France).
ScFv was further affinity purified using an anti c-myc tag mAb commercially denoted as 9E10 IgG.
For the detection antibody, IgG-purified anti-HNG sera was further affinity purified using an HNG-conjugated ligand affinity column and subsequently labeled with biotin.
The crude antisera were purified sequentially, first by affinity chromatography on protein A and G sepharose columns and subsequent further affinity purification using the immobilized peptide antigens, as previously described for anti-Tensin2 [5].
Further affinity purification of this activity identified a novel, 140-kDa protein that was sequenced and named Tat-SF1 (accession number NP_055315; HUGO gene name HTAT-SF1).
Using the current methodology, we identified the major lipid hydroperoxide-mediated modifications to proteins in MCF-7 cells without the need for chemical labeling or further affinity purification.
