Introducing the Anti-Mouse/Human CD49d [PS/2] In Vivo Antibody - Low Endotoxin from Assay Genie, a highly specific monoclonal antibody designed for in vivo applications.
This antibody targets the CD49d protein, integral to leukocyte migration and adhesion processes, making it ideal for research in immunology and related fields. With a rat IgG2b isotype, it ensures high purity and low endotoxin levels (<1.0 EU/mg), perfect for ELISA, flow cytometry, and in vivo functional assays. Available in various sizes, it is formulated in phosphate-buffered saline for stability and efficacy. Enhance your research with this reliable and versatile antibody. CD49d, also known as integrin alpha-4, is a transmembrane glycoprotein expressed on the surface of various immune cells including T-lymphocytes, B-lymphocytes, monocytes, and eosinophils. It plays a crucial role in the immune system by mediating cell adhesion and migration, particularly through interactions with vascular cell adhesion molecule-1 (VCAM-1) and the extracellular matrix.

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.
