Chemotaxis Assay, Springer Lab. A chemotaxis assay's function is to assess whether a factor or molecule of interest has chemotactic activity on a motile cell type. Chemotaxis is the ability of a factor to cause the migration of a cell. The chemotactic assay is based on the creation of a chemical gradient of the chemotactic agent which will cause cells to migrate through the gradient towards the chemotactic agent. - [Read Chemotaxis Assay]

This chemotaxis assay protocol is based on the premise of creating a gradient of the chemotactic agent and allowing cells to migrate through a membrane towards the chemotactic agent. A chemotaxis assay can determine whether your protein or small molecule of interest has chemotactic activity on a specific cell type. Chemotaxis is then the ability of a protein to direct the migration of a specific cell. - [Read Chemotaxis Assay Protocol]

Describes methods for labeling high or low numbers of lymphocytes with CSFE. Protocols are provided to use CSFE-labeled cells in cell transfer studies or as cells to be cultured in vitro. Detailed guidelines for positioning of CSFE-labeled lymphocytes in lymphoid organs or other tissues are included for those wishing to use this approach to study lymphocyte migration. - [Read Intracellular Fluorescent Dye CFSE to Monitor Lymphocyte Migration and Proliferation]

Protocol demonstrates that reactive astrocytes play a crucial role in wound healing and functional recovery by using mice with a selective deletion of the signal transducer and activator of transcription-3 (STAT3) or suppression of cytokine signaling-3 (SOCS3) under the control of Nestin gene promoter/enhancer (STAT3N–/–, SOCS3N–/–). Procedure includes: Surgical procedures, Functional evaluation, Immunohistochemistry, In vitro migration assay. - [Read Protocol for Conditional Ablation of stat3/socs3 Discloses the Dual Role for Reactive Astrocytes]

TransWell Chemotaxis protocol. trans-well chemotaxis method from bioprotocol. The protocol is a method for studying migration towards a concentration gradient of chemoattractant of leukocytes (neutrophils, monocytes and lymphocytes) or other migratory cells. An upper chamber containing a suspension of cells is separated by a membrane from a lower chamber containing medium with chemoattractant. Chemotaxis of the cells from the upper chamber into the lower chamber can be quantified. - [Read TransWell Chemotaxis Protocol.]
