Applications & Dilutions

Applications Tested Dillution Protocol Note
Immunohistochemistry (IHC)
30 min at RT. Staining of formalin-fixed tissues requires heating tissue sections in 10mM Tris with 1mM EDTA, pH 9.0, for 45 min at 95°C followed by cooling at RT for 20 minutes


Laminins, a family of extracellular matrix glycoproteins, are the major non-collagenous constituent of basement membranes. They have been implicated in a wide variety of biological processes including cell adhesion, differentiation, migration, signaling, neurite outgrowth and metastasis. Many of the effects of laminin are mediated through interactions with cell surface receptors. These receptors include members of the integrin family, as well as non-integrin laminin-binding proteins. This gene encodes a high-affinity, non-integrin family, laminin receptor 1. Reportedly, level of laminin receptor transcript is higher in colon carcinoma tissue and lung cancer cell line than their normal counterparts. Also, there is a correlation between the upregulation of this polypeptide in cancer cells and their invasive and metastatic phenotype.

  • Required for the assembly and/or stability of the 40S ribosomal subunit. Required for the processing of the 20S rRNA-precursor to mature 18S rRNA in a late step of the maturation of 40S ribosomal subunits. Also functions as a cell surface receptor for laminin. Plays a role in cell adhesion to the basement membrane and in the consequent activation of signaling transduction pathways. May play a role in cell fate determination and tissue morphogenesis. Acts as a PPP1R16B-dependent substrate of PPP1CA.
  • (Microbial infection) Acts as a receptor for the Adeno-associated viruses 2,3,8 and 9.
  • (Microbial infection) Acts as a receptor for the Dengue virus.
  • (Microbial infection) Acts as a receptor for the Sindbis virus.
  • (Microbial infection) Acts as a receptor for the Venezuelan equine encephalitis virus.
  • (Microbial infection) Acts as a receptor for the pathogenic prion protein.
  • (Microbial infection) Acts as a receptor for bacteria.
