From a routine-profiling viewpoint, the FLIPR-based

Growth of the Label-Free Platform to
Measure B Cell Activation
As stated, RL is usually a human non-Hodgkin��s lymphoma B
cell line. RL cells express the integrin LFA-1, and associa-
tion with its ligand ICAM-1 mediates B cell adhesion. The
propensity for LFA-1 to associate with ICAM-1 is largely
dependent about the conversion of LFA-1 to an intermediate-
affinity conformation (Fig. 1).

The signaling cascades
elicited on BCR activation contribute for the conformational
shift needed for LFA-1/ICAM-1 interactions.

The princi-ple with the EPIC platform is depending on association of LFA-1
expressing RL cells to ICAM-1 coated to the EPIC plate
(Suppl. Fig. 3). We hypothesized that treatment method of RL cells
with anti-IgM should really shift LFA-1 expressed in RL cells to
an intermediate conformation capable of associating with
ICAM-1 rendered to the EPIC plate. Treatment of RL cells
with inhibitors with the BCR signaling pathway ought to abro-
gate the LFA-1/ICAM-1 association (Suppl. Fig. 3). RL
cells were seeded onto 384-well EPIC plates precoated with
or without the need of ICAM-1 and permitted to equilibrate for approxi-
mately 2 h in the EPIC. The equilibration time permitted the
cells to Akt inhibitor Sigma settle, leading to a steady-state baseline.

Addition
of anti-IgM elicited a beneficial shift in response that corre-
sponded to an increased mass within the sensing volume in wells coated with ICAM-1 (Fig. 3A). The peak response
was somewhere around 25 min submit anti-IgM application, fol-
lowed by a slow decay (Fig. 3A). The slow decay and
decreased mass inside the sensing volume would recommend
the probable release of RL cells in the ICAM-1-coated
surface. From a practical standpoint, this will be con-
sistent with immune cell extravasion and endothelial migra-
tion. Without a doubt, the erythromyeloblastoid leukemia cell line,
K562, is reported to show dynamic LFA-1/ICAM-1 adhe-
strengthening that Omecamtiv mecarbil facilitates extravasion and transmigra-
