Screening and epitope characterization of Nidogen‐2‐specific nanobodies

FEBS Open Bio, EarlyView.
Camel immunization and phage display were employed to generate high‐affinity VHH nanobodies against Nidogen‐2. After library construction, biopanning, ELISA screening, sequencing, and recombinant expression, selected nanobodies were purified and characterized, leading to the preliminary exploration of a nanobody‐based sandwich ELISA for specific ...

Kinetic Measurement of the Erythrocyte Sedimentation Rate

Upsala Journal of Medical Sciences, 1994
A method for estimation of the erythrocyte sedimentation from repeated measurements during the initial part of the sedimentation phase is described. Based on the measurements between 18 and 24 minutes after the beginning of the reaction, the sedimentation at 60 minutes is estimated.

Modeling of Knudsen layer effects in micro/nanoscale gas flows [PDF]

, 2011
We propose a power-law based effective mean free path (MFP) model so that the Navier-Stokes-Fourier equations can be employed for the transition-regime flows typical of gas micro/nanodevices.

Rapid screening of staphylokinase protein variants using an unpurified cell‐free expression system

FEBS Open Bio, EarlyView.
An unpurified cell‐free protein synthesis (CFPS) platform enables rapid functional screening of staphylokinase variants. Direct plasminogen‐activation assays performed in microplate format provide real‐time activity readouts, allowing rapid identification and ranking of variants with improved or reduced fibrinolytic activity without protein ...
