The CD4 cd4 (Catalog #MBS8501468) is an Antibody produced from Mouse and is intended for research purposes only. The product is available for immediate purchase. The Mouse anti-Human CD4, APC Conjugated mAb reacts with Human and may cross-react with other species as described in the data sheet. MyBioSource\'s CD4 can be used in a range of immunoassay formats including, but not limited to, Flow Cytometry (FC/FACS), Immunoprecipitation (IP), Immunofluorescence (IF), Immunohistochemistry (IHC). Researchers should empirically determine the suitability of the CD4 cd4 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process.The CD4 cd4 product has the following accession number(s) (GI #3947700) (NCBI Accession #CAA60883.1) (Uniprot Accession #Q13969). Researchers may be interested in using Bioinformatics databases such as those available at The National Center for Biotechnology Information (NCBI) website for more information about accession numbers and the proteins they represent. Even researchers unfamiliar with bioinformatics databases will find the NCBI databases to be quite user friendly and useful.

CD4, also known as T4, is a 55 kD single chain transmembrane glycoprotein and belongs to immunoglobulin superfamily. CD4 is found on most thymocytes, a subset of T cells and at low level on monocytes/macrophages.CD4 is a co-receptor involved in immune response (co-receptor activity in binding to MHC class II molecules) and HIV infection (CD4 is primary receptor for HIV-1 surface glycoprotein gp120). CD4 regulates T-cell activation, T/B-cell adhesion, T-cell diferentiation, T-cell selection and signal transduction.
Experimental Methods: 1. 1.Take 100mul peripheral blood anticoagulated by EDTA and add to the bottom of 5ml tube;
2.Add 10mul labeled antibody to the bottom of flow tube mixing with the whole blood, incubate for 20 minutes at room temperature away from light;
3.Add 2 ml1�RBC lysis buffer, incubate for 10 minutes away from light after mixing, dissolve red blood cells (recommended: RBC lysing Solution 10�);
4.Sample tube is set to 1000 rpm centrifugation for 5 minutes, discard the supernatant;
5.Add 2 ml PBS wash buffer to resuspend the cells, then1000 rpm centrifugation for 5 minutes, discard the supernatant;
6.Add appropriate amount of fluorescent-labeled Streptavidin and incubate for 20 minutes away from light at room temperature.
7.Repeat step 5.
8.Add 0.5 ml PBS wash buffer to resuspend the cells and detect by flow cytometry (sample should be determined on the day on the machine and can also be added fixation overnight at 4 degree C then measured).
[PBS wash buffer: PBS +1% FBS +0.1% NaN3]
[Cell fixation: 2% formaldehyde solution]. In general, we may offer more than one antibody to a given target to enable options for the researcher. Available antibodies recognizing CD4 are readily searchable from our website. Different antibodies against the same target such as CD4 may be optimized or tested for different applications and species. This enables researchers to select the option that may be best for their model system, to screen more than antibody to determine which one may be best for their model system, as well as to use more than one antibody to follow up on and validate their results.
