Thank you for contacting Abcam. The anti-Pig Albumin antibody has not previously been tested in ICC/IF and so we have no standard protocol for this particular antibody, but I have looked over the protocol you sent and have a few questions/tips that may help. 1 - Have you tried staining a pure culture of porcine periodontal ligament epithelial cells and not just a mixed culture? I ask in case there is a possibility that your cells of interest are not surviving in the culture. 2 - Incubating the primary and secondary antibody in PBS rather than the blocking solution, can help increase staining. 3 - You are fixing for 20 minutes in 4% PFA, have you tried fixing for less time, maybe 10-12 minutes. Over fixation of a sample can prevent the antibody from binding to its target. 4 - Using a different blocking solution, either 10% BSA or horse serum etc, could help. Hopefully some of the above suggestions will help resolve the no staining problem. If there is anything  else I can do, please do not hesitate to contact me.
