We are trouble-shooting cryosectioning mouse lung tissue. Often the lung section tears or breaks apart during sectioning. In the past, if the lung section is proving difficult to section, we take the OCT-embedded tissue and re-embed it back into OCT (basically put fresh OCT into the original

Hi, We are performing some immunofluorescence staining on mouse lung tissue. We are getting some nice positive staining with some of our initial antibodies (procollagen, cytokeratin). We would like to minimize the amount of background staining we are getting. We are titering our primary
