Human Anti-RSV Recombinant Antibody (clone B21m) (CAT#: PABL-693)

Recombinant Human Antibody (B21m) is capable of binding to RSV, expressed in HEK 293 cells. Expressed as the combination of a heavy chain (HC) containing VH from anti-RSV mAb and CH1-3 region of human IgG1 and a light chain (LC) encoding VL from anti-RSV proteins mAb and CL of human kappa light chain. Exists as a disulfide linked dimer of the HC and LC hetero-dimer under non-reducing condition.

(A) wild-type (WT); (B) N434A or (C) N434Y were diluted 1:5 in a concentration series from 1000 to 1.6 nM, injected over rat FcRn for 1 min in PBS-TE (pH 6.0) and followed immediately by a co-injection of PBS-TE (pH 7.4) without mAb for 3 min.

Figure 2 Greatest serum levels of IgG measured when administered at site with greatest rat FcRn mRNA expression.

(A) Serum levels of the WT mAb were measured after 90 min following administration at the proximal small intestine (S.I; duodenal region) and at the distal S.I (ileum region) in suckling rat pups (n = 6). A one-way ANOVA followed by Bonferroni's multiple comparison test was carried out versus respective WT. (B) mRNA expression of rat FcRn, assessed using reverse transcription polymerase chain reaction (RT-PCR), from mucosal scrapings of proximal and distal small intestine, and proximal and distal colon. Data shown is fold change over proximal colon which had the lowest level of FcRn mRNA).
