The anti-Pu.1 rabbit polyclonal antibody was generated in-house against the N-terminus of Pu.1 (aa. 1-100; NP_035485.1) 32 (link). Antibodies used in western blot experiments: Stat1 (#9172), phospo-Stat1 (Tyr701, #9171), Stat6 (#9362), phospho-Stat6 (Tyr641, #9361), Erk1/2 (#9102), phospho-Erk1/2 (Thr202/Tyr204, #9101), phospho-Akt (Ser473, #9271); anti-actin (A4700) from Sigma-Aldrich.

OVA-Specific Antibody and Cytokine Responses

Mice were immunized subcutaneously with OVA (Sigma) in CFA (Sigma) and euthanized after 14 days. Blood was collected and allowed to coagulate in the refrigerator in Microtainer Serum Separator tube (BD). Serum was isolated by centrifugation. For ELISA to detect OVA-specific Ig, plates were coated with 2 mg ml−1 OVA. Antibody levels in serially diluted serum samples were analysed with HRP-conjugated antibodies (1:4,000) specific for mouse IgM (1021-05), IgG (1030-05), IgG1 (1070-05), and IgG2c (1079-05) (SouthernBiotech) following manufacture's recommended protocols. For ex vivo cytokine production, splenocytes were isolated 14 days following OVA-CFA immunization and cultured in the presence of OVA (100 μg ml−1). ELISAs were performed with purified anti-IFNγ (Biolegend 505707) and anti-IL-4 mAb (Biolegend 504102) as capture antibodies, the corresponding biotinylated anti-IFNγ (Biolegend 505804, 1 μg ml−1)and anti-IL-4 mAb (BD Biosciences 554390 1 μg ml−1), horseradish peroxidase-conjugated streptavidin (Sigma), and the TMB microwell peroxidase substrate and stop solution (Kirkegaard & Perry Labs, Inc.) according to the recommended protocol (Biolegend). Recombinant mouse IFNγ and IL-4 (R&D Systems) was used as standards.

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.
