Article Title: PseudoFab-based multispecific binding proteins
Article Snippet: .. For determination of its thermal stability, the ds-trastuzumab domains were incubated at a concentration of 1 mg/mL in D-PBS buffer (GIBCO) for 14 days at 40° C. Control samples at the same concentration were kept at −80° C. and 4° C. After completion of the stress test, the samples were analyzed for their aggregate content by analytical size exclusion chromatography (SEC). .. Analytical SEC was performed using a BioSECcurity instrument (PSS Polymer) with a TSKgel SuperSW3000 column (4.6 mm×300 mm) and TSKgel SuperSW HPLC guard column (Tosoh Bioscience) at 25° C. The analysis was run at a flow rate of 0.25 ml/min using 250 mM NaCl, 100 mM Na-phosphate pH 6.7 with detection at 280 nm and 260 nm.
Incubation:Article Title: Bispecific anti-CD28 × anti-CD22 antibodies and uses thereof
Article Snippet: .. After incubation, cells were washed once with cold D-PBS buffer without FBS and incubated with LIVE/DEAD Fixable Green Dead Cell Stain (Invitrogen) according to manufacturer's instructions to discriminate between live and dead cells. .. Cells were then fixed in BD Cytofix Buffer according to manufacturer's instructions, washed, re-suspended in staining buffer, and analyzed by flow cytometry on an iQue Screener flow cytometer.
