    Wednesday, May 05, 2004 Description Protocol for intracytoplasmic staining of cytokines for FACS analysis Procedure 1) Prepare spleen, lymph node or T cell clone cells as single cell suspension, using erythrocyte lysis (water) or Lymphopaq...

  • [Immunology] FACS STAINING OF PBLs for monitoring CD4 and CD8 depletion 日期:2005-07-18 00:00:00 点击:239 好评:0

    Wednesday, May 05, 2004 Description This method is useful for monitoring depletion in vivo using rat IgG2b monoclonal antibodies against CD4 and CD8. The indirect staining method, using a monoclonal reagent that does not give any backgroun...

  • [Immunology] Preabsorbing Antisera with C. elegans Acetone Powder 日期:2005-07-18 00:00:00 点击:200 好评:0

    Monday, May 03, 2004 Description One way to eliminate crossreactivity of a polyclonal antiserum raised against a worm protein is to preabsorb the antiserum against total protein extracted from a worm mutant that does not produce that speci...

  • [Immunology] Protocol for Metal Enhanced DAB Staining using HRP 2 Antibod 日期:2005-07-18 00:00:00 点击:470 好评:0

    Monday, May 03, 2004 Description Protocol for Metal Enhanced DAB Staining using HRP 2 Antibodies Procedure 1. Carry out the fixation, permeabilization, and primary antibody incubation steps exactly as described above for the FITC detection...

  • [Immunology] Antibody Staining of C. elegans 日期:2005-07-18 00:00:00 点击:793 好评:0

    Description This protocol works for many antibodies. A much longer protocol involving collagenase treatment of the worms is necessary for some antisera (e.g. anti-serotonin). Dauers are not permeabilized by this protocol and thus don't sta...
