This protocol describes a method to assess concentrations of free cytoplasmic calcium (Ca2+) in mouse splenic B cells in the absence and presence of ligands for cell surface receptors. This objective is accomplished with the Ca2+-sensitive fluorescent dye, Fluo-3, which permeates cells as an ester and is hydrolyzed in the cell to its Ca2+ sensitive acidic form. - [Read Assay of Intracellular Free Calcium in Suspended B Cells]

Immunostaining thin layer chromatograms TLC is a very sensitive detection technique of functionally active carbohydrate ligands of protein receptors. Carbohydrate structures are detected in glycolipids from complex mixtures of molecules extracted from the relevant target tissue. Proteins analyzed can be antibodies, chimeric Ig proteins, selectins, lectins, toxins, and other carbohydrate binding proteins. John L. Magnani~GlycoTech Corporation, Rockville, Maryland - [Read Immunostaining Thin Layer Chromatograms Of Glycolipids]

Protocol describes a competitive ligand binding assay for cortical neurotrophin receptors. Following binding in the presence of competitor, the bound radiolabeled ligand is cross-linked to the receptor. The cells are lysed and the ligand-receptor complexes are immunoprecipitated using a pan-trk (tyrosine kinase receptor) antibody. Protocol includes:Preparation of Cortical Tissue for Competitive Crosslinking, Competitive Binding, Crosslinking Ligand to Receptor, Lysis and Immunoprecipitation etc - [Read Protocol for Competitive Ligand Binding to Cortical Receptor using Crosslinking]

Matirgel is considered as basement membrane and generated from EHS sarcoma. Matrigel contains not only basement membrane components (collagens, laminin, and proteoglycans)but also matrix degrading enzymes/their inhibitors and growth factors. Invasion of tumor cells into Matrigel has been used to characterize involvement of ECM receptors and matrix degrading enzymes which play roles in tumor progression. - [Read Protocol for Matrigel Invasion Assays]

This protocol uses mitogen-activated protein/ERK kinase (MEK) to activate the extracellular-signal-regulated (Erk) mitogen-activated protein (MAP) kinases upon agonist binding to receptors. Protocol includes information about: Harvest, Immunoprecipitation and Kinase Reaction. Also includes following solutions: Laemmli Sample Buffer (1X), ATP Mix, Kinase Buffer (10X), Lysis Buffer. Helpful protocol hints are also included. - [Read Raf-1 Kinase Assay]
