Isolation of Murine Alveolar Type II Epithelial Cells
[Abstract]  We have optimized a protocol for isolation of alveolar type II epithelial cells from mouse lung. Lung cell suspensions are prepared by intratracheal instillation of dispase and agarose followed by mechanical disaggregation of the lungs. Alveolar type II epithelial cells are purified from these lung cell suspensions through magnetic-based negative selection using a Biotin-antibody, Streptavidin-MicroBeads system. The purified alveolar type II epithelial cells can be cultured and maintained on ...

Simultaneous Intranasal/Intravascular Antibody Labeling of CD4+ T Cells in Mouse Lungs
[Abstract]  CD4+ T cell responses have been shown to be protective in many respiratory virus infections. In the respiratory tract, CD4+ T cells include cells in the airway and parenchyma and cells adhering to the pulmonary vasculature. Here we discuss in detail the methods that are useful for characterizing CD4+ T cells in different anatomic locations in mouse lungs.

Cell-to-cell DNA Transfer among Thermus Species
[Abstract]  The ability to transfer DNA via direct cell-to-cell contact-dependent process similar to conjugation has been described in Thermus thermophilus (Tth). Here, we detail the mating experiment protocol involving the lateral transfer of thermostable antibiotic resistance markers (i.e., kanamycin: KmR; hygromycin: HygR) between Thermus cells, enabling the selection and quantification of the transfer frequencies. Briefly, liquid cultures of both mates ...
