Check if the same lab product or an alternative is used in the 5 most similar protocols
PAMs seeded in 12-well plates were infected with ASFV (MOI = 0.1) and fixed at 48 h post-infection with 4% paraformaldehyde (PFA) for 30 min at room temperature. Then the fixed cells were permeabilized with 0.2% Triton X-100 in PBS for 10 min at room temperature. 2% BSA in PBS was used to block the permeabilized cells for 3 h at room temperature. Anti-p30 antibody, anti-ASFV antibody positive serum, and the six generated anti-rpI215L mAbs were used, respectively, as primary antibodies to incubate the fixed cells for 2 h at room temperature. Coralite488-conjugated Affinipure Goat Anti-Mouse IgG(H + L) (Proteintech Group, Inc., Rosemont, IL, USA) was used as the secondary antibody to incubate the cells for 50 min at 37 °C. Five washes with PBS were performed after each of the above steps. Finally, the cells were observed and photographed by Zeiss Axio Observer (Carl Zeiss, Jena, Germany). Experiments with live ASFV were performed in the Biosafety Level 3 Laboratory of Lanzhou Veterinary Research Institute.

To evaluate the inflammation and epidermal regeneration in the wound area, tissues containing the wound site and their surrounding healthy skin were collected. The tissue samples were fixed in 4% (v/v) paraformaldehyde for 1 h right after sacrifice before embedded in paraffin. The samples were cross sectioned to slices (4 μm thickness) and then stained by Hematoxylin-Eosin (H&E). All slides were scanned and analyzed by a Digital Slide Scanner (KFBIO, Ningbo). The regenerated skins from the wound site were also excised for IF staining with Anti-VEGFA antibody (proteintech) and TNFA Ab (proteintech), respectively. CoraLite488-conjugated Affinipure Goat Anti-Mouse IgG(H + L) (proteintech) and CoraLite594-conjugated Goat Anti-Rabbit IgG(H + L) (proteintech) were used as the secondary antibody to reveal VEGFA and TNFA expression.

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.
