Anti-Human CD4 (Clone OKT-4) In Vivo Antibody

Product Name:	Anti-Human CD4 (Clone OKT-4) In Vivo Antibody - Ultra Low Endotoxin
Product Code:	IVMB0350
Size:	1 mg, 5 mg, 25 mg, 50 mg, 100 mg
Clone:	OKT-4
Protein:	CD4
Product Type:	Monoclonal Antibody
Synonyms:	CD4; T4; CD4 antigen (p55); CD4 antigen p55; CD4 receptor; T-cell surface antigen T4/Leu-3; T-cell surface glycoprotein CD4
Isotype:	IgG2b k
Reactivity:	Human
Applications:	ELISA, FC, ICC, IF Staining, IHC FF, IHC FFPE, In Vivo, IP, N, PhenoCycler®, WB
Formulation:	This monoclonal antibody is aseptically packaged and formulated in 0.01 M phosphate buffered saline (150 mM NaCl) PBS pH 7.2 - 7.4 with no carrier protein, potassium, calcium or preservatives added. Due to inherent biochemical properties of antibodies, certain products may be prone to precipitation over time. Precipitation may be removed by aseptic centrifugation and/or filtration.
Endotoxin Level:	<0.5 EU/mg as determined by the LAL method
Purity:	≥98% monomer by analytical SEC ⋅ >95% by SDS Page
Product Preparation:	Functional grade preclinical antibodies are manufactured in an animal free facility using in vitro cell culture techniques and are purified by a multi-step process including the use of protein A or G to assure extremely low levels of endotoxins, leachable protein A or aggregates.

Applications:	ELISA, FC, ICC, IF Staining, IHC FF, IHC FFPE, In Vivo, IP, N, PhenoCycler®, WB
Reactivity:	Human

Host Species:	Mouse
Specificity:	Clone OKT4 recognizes Human CD4. This clone recognizes a different epitope than the RPA-T4 monoclonal antibody, and these antibodies do not interfere with each other.
Antigen Distribution:	CD4 is expressed on most thymocytes, a subset of T cells, and monocytes/macrophages, and may be detected in thymus, lymph nodes, tonsils, and spleen, and also in specific regions of the brain, gut, and other non-lymphoid tissues.
Immunogen:	Human peripheral T cells
Endotoxin Level:	<0.5 EU/mg as determined by the LAL method

Storage and Handling:	Functional grade preclinical antibodies may be stored sterile as received at 2-8°C for up to one month. For longer term storage, aseptically aliquot in working volumes without diluting and store at -80°C. Avoid Repeated Freeze Thaw Cycles.

CD4 is a 55 kD single-chain type I transmembrane glycoprotein and a member of the Ig superfamily. It is involved in the recognition of MHC class II molecules. Furthermore, CD4 is the primary receptor for HIV. CD4 initiates the early phase of T-cell activation via its association with the T-cell receptor complex and protein tyrosine kinase, Lck. In addition, CD4 functions as a mediator of direct neuronal damage in infectious and immune-mediated diseases of the central nervous system.

Protein:	CD4
Pathogen Testing:	To protect mouse colonies from infection by pathogens and to assure that experimental preclinical data is not affected by such pathogens, all of Assay Genie's Purified Functional Antibodies are tested and guaranteed to be negative for all pathogens in the IDEXX IMPACT I Mouse Profile.
