Description

Rat Monoclonal Antibody

The GK1.5 monoclonal antibody reacts with the mouse CD4 molecule, a 55 kDa cell surface receptor expressed by a majority of thymocytes, subpopulation of mature T cells and dendritic cells. CD4 binds to MHC class II on the surface of antigen presenting cells and plays an important role both in T cell development and in optimal functioning of mature T cells. In T cells, CD4 associates with protein tyrosine kinase p56lck through its cytoplasmic tail. Binding of GK1.5 is blocked by RM4-5. This product contains 1 vial of NovaFluor conjugate and 1 vial of CellBlox Plus Blocking Buffer. Applications Tested This GK1.5 antibody has been tested by flow cytometric analysis of mouse splenocytes. This can be used at less than or equal to 0.2 μg per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Master mixes Master mixes of NFs should be made at 2-8 °C and may be made up to 4 hours ahead of time. We do not recommend storing master mixes containing NovaFluor conjugates overnight or longer. Whole Blood compatibility When utilizing whole blood (as opposed to density-gradient-purified PBMC), we recommend lysing red blood cells in bulk prior to...

The CD4 antigen is involved in the recognition of MHC class II molecules and is a co-receptor for HIV. CD4 is primarily expressed in a subset of T-lymphocytes, also referred to as T helper cells, but may also be expressed by other cells in the immune system, such as monocytes, macrophages, and dendritic cells. At the tissue level, CD4 expression may be detected in thymus, lymph nodes, tonsils, and spleen, and also in specific regions of the brain, gut, and other non-lymphoid tissues. CD4 functions to initiate or augment the early phase of T-cell activation through its association with the T-cell receptor complex and protein tyrosine kinase, Lck. It may also function as an important mediator of direct neuronal damage in infectious and immune-mediated diseases of the central nervous system. Multiple alternatively spliced transcripts have been identified in this gene [RefSeq, July 2017].

Frequently Asked Questions (FAQs)

What fixation methods are compatible with NovaFluor dyes?

NovaFluor conjugates have been tested to be stable for up to 14 days on cells fixed with 1% formalin, 2% paraformaldehyde, eBioscience IC Fixation Buffer (Cat. No. 00-8222-49), or eBioscience Foxp3 / Transcription Factor Staining Buffer Set (Cat. No. 00-5523-00) when stored at 2-8 degrees C in the dark.

NovaFluor dyes can also be used as a surface stain prior to methanol fixation.
