IgG Induction by IL-33 and anti-IgM/CD40L

Check if the same lab product or an alternative is used in the 5 most similar protocols
Peripheral blood mononuclear cells (PBMCs) were isolated from heparinized peripheral blood using Ficoll-Paque density gradient (GE Healthcare). PBMCs were washed with phosphate-buffered saline (PBS) and cultured in RPMI 1640 medium with 10 % FCS and 1 % glutamine/penicillin/streptomycin (Life Technologies). Recombinant human IL-33 protein was purchased from R&D Systems. Anti-human IgM antibody was purchased from eBioscience. Recombinant human CD40 Ligand (CD40L) was purchased from Life Technologies. For in vitro induction of anti-RBC IgG antibody, PBMCs (1 × 106/ml) were cultured with anti-IgM (10 μg/ml) and CD40L (10 ng/ml) in the presence or absence of IL-33 (0–20 ng/ml). Six days later, the supernatants were collected and assayed for IgG antibodies with Human IgG total ELISA kit (eBioscience).

Human IgG total ELISA Kit (Invitrogen, Thermo Fisher Scientific, Waltham, MA) was used to measure total IgG concentration in cell culture supernatant, according to the manufacturer’s instruction. Optical density were measured at 450 nm using a 1420 multilabel counter (PerkinElmer life and analytical sciences, Boston, MA).

Recombinant Protein Release Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
For recombinant protein release analysis, cells were cultured in a T75 cm2 culture flask. Once 75% confluency was reached, cells were washed with HBSS and incubated in 5 mL of fresh GM for 2 h at 37°C in a standard incubator. The medium was then collected for quantification and cells were counted using an automated cell counter. Three ELISA kits were used for supernatant analysis: a GM-CSF Human ELISA Kit with a lower limit of quantification at 7.8 pg/mL (Thermo Fisher Scientific, KHC2011), a GM-CSF Mouse ELISA Kit (Thermo Fisher Scientific, BMS612), and an IgG (Total) Human ELISA Kit (Thermo Fisher Scientific, BMS2091). All kits were used according to the manufacturers’ instructions. Results were reported in pg/cell/day.

Optimizing Rituximab Production in CHO Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Samples were collected from days 1,
3, 5, 7, and 8 of a fed-batch
cultivation carried out in a 4 L benchtop bioreactor (Belach Bioteknik,
Stockholm, Sweden). The cells were Rituximab-producing Chinese hamster
ovary cells (TurboCellTM, kindly provided by Rentschler Biopharma,
Laupheim, Germany). The base and feed media were chemically defined
proprietary media without animal-derived components. CHO HCP concentrations
were quantified using a CHO HCP ELISA kit, 3G (F550) from Cygnus Technologies.
Rituximab concentrations were quantified using an IgG (total) Human
ELISA kit (BMS2091) from Thermo Fisher Scientific and purified Rituximab
as internal standard. For both ELISA kits, all samples and calibration
wells were measured in duplicate according to the instructions from
the suppliers. LDH concentrations were determined with triplicate
measurements from centrifuged (180g for 5 min) samples
with Cedex Bio Analyzer (Roche Diagnostics Deutschland GmbH, Mannheim,
Germany).

Quantitative IgG and IgM ELISA

Check if the same lab product or an alternative is used in the 5 most similar protocols
Total IgG and IgM levels in culture supernatants were determined using an IgG total human ELISA kit (Thermo Fisher Scientific) and an ELISA Flex: Human IgM (ALP) kit (MABTECH, Nacka Strand, Sweden), respectively. For IgM detection, pNPP (MABTECH, Nacka Strand, Sweden) was used as the substrate for the ALP signal detection. Both assays were performed in accordance with the manufacturer's instructions.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
