Purified PDCoV S1 protein with an Fc-tag was subjected to 12% SDS-PAGE and then transferred to a nitrocellulose (NC) membrane. The NC membrane was blocked using 5% (w/v) nonfat dried milk in phosphate-buffered saline (PBS) at 37 °C for 1 h and then incubated with a rabbit monoclonal antibody (mAb) against the Fc tag (1:20,000) and a porcine polyclonal antibody (pAb) against PDCoV (1:500) at 37 °C for 1 h. After washing three times with PBS containing 0.05% Tween 20 (PBST), the membrane was incubated in PBS containing horseradish peroxidase (HRP)-conjugated goat anti-rabbit (1:10,000) (Sigma) or rabbit anti-pig IgG (1:10,000) (Sigma) at 37 °C for 1 h. Membranes were washed with PBST and incubated with substrate solution (PBST, 0.05% DAB and 0.006% H2O2).

Polyclonal Antibody Production against BmCPV VP7

Check if the same lab product or an alternative is used in the 5 most similar protocols
To prepare polyclonal antibody against VP7 proteins of BmCPV, the cDNA with primers listed in Table 1 was amplified with PCR. The amplified PCR products were ligated into the prokaryotic expression vector pET28(a). The recombinant prokaryotic expression vector pET28(a)-vp7 (Supplementary Fig. 1A) was transformed into Escherichia coli strain BL21 cells and induced with 1 mmol/L isopropyl-β-d-thiogalactopyranoside (IPTG). After 4 h of induction, 1.5 ml of the transformed BL21 cells was collected for the recombinant protein detection. The proteins were detected with sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and western blotting (Supplementary Fig. 1B), using a primary antibody of rabbit anti-6 × His (Sigma) and a secondary antibody of horseradish peroxidase (HRP)-conjugated goat anti-rabbit (Sigma). Recombinant protein (VP7) was purified from the 1 L BL21 cells with Ni-NTA (Ni2 +-nitrilotriacetate) resin (Invitrogen, Carlsbad, CA) using standard procedure. Mouse was immunized with recombinant protein (VP7) for preparing the VP7 polyclonal antibody. Booster injections were administered according to the manufacturer's instructions. The collected serum was stored at − 70 °C.

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.
