Anti-Mouse/Human CD49d [PS/2] In Vivo Antibody - Ultra Low Endotoxin
Introducing the Anti-Mouse/Human CD49d [PS/2] In Vivo Antibody - Ultra Low Endotoxin from Assay Genie, a highly specific monoclonal antibody meticulously designed for in vivo studies. This antibody targets the CD49d protein, a pivotal component in leukocyte adhesion and migration, making it indispensable for research in immunology and related fields. Featuring a rat IgG2b kappa isotype, this antibody ensures ultra-low endotoxin levels (<1.0 EU/mg), guaranteeing high purity and suitability for a range of assays including ELISA, flow cytometry, and immunohistochemistry.
Available in multiple sizes, it is formulated in phosphate-buffered saline to maintain stability and efficacy. Propel your research forward with this reliable and versatile antibody. CD49d, also known as integrin alpha-4, is a protein expressed on the surface of leukocytes, including T-cells, B-cells, and monocytes. It plays a crucial role in the immune system by mediating cell adhesion to VCAM-1 and fibronectin, facilitating leukocyte trafficking, and participating in inflammatory responses.

Integrins are a large family of heterodimeric transmembrane molecules that mediate adhesion, migration, cell survival, and cell differentiation. CD49d is a single-pass type I membrane glycoprotein also known as integrin alpha-4 (Uniprot Accession P13612). CD49d is the α4 subunit of integrin heterodimers alpha-4/beta-1 (VLA-4; CD49d/CD29; α4β1 integrin) and alph-4/beta-7 (LPAM-1)1. These integrins act as receptors for fibronectin and VCAM1 (CD106). Integrin alpha-4/beta-7 is also a receptor for MADCAM1.
CD49d is expressed on most lymphocytes, granulocytes, monocytes, and thymocytes. CD49d/CD29 (VLA-4; α4β1) is expressed at high levels on the surface of lymphohematopoietic progenitors and is involved in their development and proliferation. CD49d/CD29 integrin/VCAM-1 interactions facilitate B cell adhesion to stromal cells and enhance B cell activation. In the absence of alpha-4 integrins, pre-B cells fail to transmigrate and proliferate.
PS/2 recognizes murine and human CD49d2. PS/2 was generated by immunizing Fisher rats with P815 cells and subsequently fusing the spleen cells with Sp2/0. Hybridoma supernatants were screened by cell adhesion assay and cells producing blocking antibodies were cloned. Adhesion is blocked in a dose dependent manner when PS/2 is used with P815 and +/+ 2.4 stromal cells. 70Z/3 cells are also sensitive to PS/2 inhibition. PS/2 is known to block binding of CD49d to its ligands3. Lymphocyte production is completely blocked when PS/2 is included in Whitlock-Witte culture2. PS/2 is IgG2b κ.
Protein:
CD49D
Function:
Lymphocyte migration, T cell activation, stem cell differentiation.
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.
