  ANTIBODIES  

(anti-Human and others as indicated)

RDI Divison of researchd Industries Intl  offers a wide line of  antibodies. Since no one antibody works best for all applications (neutralization, blotting, ELISA, etc), we offer many different types of antibodies to help solve this problem. Please inquire for other applications or types of antibodies not listed below.

Background: The catenins (alpha, beta and gamma) are cytoplasmic proteins which bind the highly conserved cytoplasmic tail of the E-Cadherin (also known as uvomorulin) molecule. Alpha catenin was first identified as an E-cadherin-associated protein; however it also appears to be able to interact with other cadherin family members such as N-cadherin, and P-Cadherin. Increased tyrosine phosphorylation of adherens junction proteins can disrupt catenin-cadherin complexes, leading to changed in cell adhesion properties. It has been noted that down regulation of this group of proteins often preceded metastasis.Recent observations show a correlation between deletions within the alpha cetenin gene and the development of prostate cancer.

Background: Beta catenin is a 92kDa protein which binds directly to the cytoplasmic region of E-cadherin. Beta-catenin is similar to plakoglobin (also known as gamma-catenin). The binding of beta-catenin seems to be required for E-cadherin function since deletions in the cytoplasmic domain of E-cadherin that eliminate catenin binding also result in a loss of cell adhesion. Recently, an unexpected link between Beta catenin and colon cancer was described. Beta catenin was found to co-immunoprecipitate with the APC tumor suppressor protein in human colorectal tumor cell lines as well as in human kidney 293 cells. E-Cadherin was not detectable in these complexes. This leads to the speculation that the APC-catenin complex may be affecting the transmission of contact inhibition signals and/or the regulation of cell adhesion.
