Category: Immunology: Mononuclear Cell Isolation Protocols

Mononuclear phagocyte progenitor cells derived from femoral and tibial bone marrow are propagated in the presence of M-CSF. This macrophage growth factor is secreted by L929 cells and is used in the form of L929 cell conditioned medium. The progenitor cells proliferate and differentiate through monoblast, promonocyte and monocyte stages before maturing to macrophages. At this time the cells become firmly adherent to the culture vessel. - [Read Isolation and Culture of Mouse Bone Marrow-Derived Macrophages Protocol]

Category: Cell Culture Protocols: Cell Storing and Cell Freezing Protocols

Protocol provides methods for cryofreezing and subsequent thawing of mammalian cells. Pre-confluent cells are trypsinized, pelleted, resuspended in freezing medium, and gradually frozen. When needed, frozen cells are thawed quickly under running tap water and transferred to growth medium. - [Read Cryopreservation of Mammalian Culture Cells: Preparation and Recovery of Samples Protocol]

Category: Immunology: Mononuclear Cell Isolation Protocols: B Lymphocyte Isolation Protocols

Protocol describes a method for isolation and stimulation of lymphocytes. Leukocyte-rich plasma is collected from whole blood and then centrifuged through Ficoll-Hypaque. The collected cells are resuspended in growth medium containing various mitogens to stimulate growth. - [Read Lymphocyte Isolation and Culture Protocol]

Category: Cell Culture Protocols: Cell Culture Contamination Prevention and Removal Protocols

This method is advantageous for saving the occasional cultures that become contaminated. Yeast contaminated cultures will appear cloudy when slightly shaken and lymphocytes will not cluster together as much as normal. If cultures are suspect, a drop of culture can be streaked on a YPD media plate to check for growth of yeast colonies, or a 5 ml sample can be taken to Barnes Diagnostic Center for identification of yeast strain. - [Read Removal of Yeast Contamination from Lymphoblast Cultures Protocol]

Category: Bacterial Cell Culture Protocols

The growth conditions of microbial cell cultures and the time of sample collection should be optimized and standardized when growing cells for protein extraction. Because cells may excrete proteases and other extracellular enzymes, and compounds in the medium may interfere with extraction, wash cultures with an isotonic buffer, such as PBS or sucrose before solubilization. - [Read Extraction and Solubilization of Total Protein from Microorganisms Protocol]

Category: Cell Biology and Cell Culture: Cell Cycle Protocols: G Phase Protocols

This protocol provides a method for synchronizing cells at the G1/S border using a double treatment of thymidine, which, in excess, is an inhibitor of DNA synthesis. Cells are treated once with excess thymidine to accumulate the majority of them at G1/S; however, some cells will have stopped growth within the S phase. - [Read G1/S Phase Synchronization using Double Thymidine Synchronization Protocols]

Category: Stem Cell Protocols: Stem Cell Culture Protocols

In vitro differentiation of ES cells occurs when the cells are allowed to aggregate in suspension culture in the absence of mouse embryonic fibroblast (MEF) feeders and leukemia inhibitory factor (LIF). Hanging drops provide a uniform aggregate size, which is then expanded by continued growth in suspension culture. The embryoid bodies are then plated and allowed to differentiate further in culture. - [Read Differentiation of Embryonic Stem (ES) Cells Using the Hanging Drop Method]

Category: Cell Biology and Cell Culture: Cell Culture Growth Media: Mammalian Cell Culture Growth Media Protocols

The culture medium is an essential component of the in vitro environment and must be selected or designed with care.
