As expected, a peptide containing proline at 405 did not bind GST-Dis1, and moreover mutated peptides that retained binding capability were those containing conservative hydrophobic residues (I, F, W, Y, and V; Figure 3E; Figure S3B).
A point mutation in FH domain 19 eliminated hemolysis caused by unmodified FH18-20, but retained binding to gonococci.
30 constructs were made, 24 expressed, and 70% of the designs using consensus sequence information retained binding affinity.
Although the obtained ADC lacked a linker, it retained binding affinity to recombinant HER2 (Kd = 0.1 0.5 nmol/L) comparable to that of the parent trastuzumab.
We demonstrated that compounds in which the amine had been exchanged for an ether or a thioether retained binding potency and selectivity.
The HBOEC-specific peptide, TPSLEQRTVYAK, when covalently coupled to a terpolymer matrix, retained binding affinity towards HBOEC in a serum-free medium.
Further, only 2 out of the 4 possible VH/VL orientations/arrangements in bDAb construction yielded active products that retain binding activity to both EGFR and IGFR.
Dimer-incapable 14-3-3 14-3-3 14-3-3ined binding caproteinsnd specificity towaretained phosphopartners, and also demonstrated increased chaperone-like activity on various subindings.
A two-step selection process, in which the light and heavy chains of the parental mAb were successively humanized, resulted in the identification of several humanized variants that retained binding to EphA2.
Single-domain antibodies (sdAbs) derived from heavy-chain only antibodies produced in camelids are attractive immunoreagents due to their small size, high affinity, and ability to refold and retain binding activity after denaturation.
