Comparison Analysis from AntibodyResource.com :
Anti-TLR4 polyclonal antibody (Catalog No. SPC-200, referenced as P133 in the report) was independently validated for use in flow cytometry on human monocytic leukemia cells (THP-1 cell line) at a 2 µg/106 cells. Read the full TLR4 antibody comparison report (PDF) prepared by AntibodyResource.comAntibody Resource is spearheading an initiative designed to compare antibodies from numerous suppliers using identical samples/tissues and an identical protocol. In doing so, they hope to enable scientists to form an unrivalled opinion of which is the most suitable antibody for their research and which is going to require the least amount of optimization, a process which can often take weeks or months. For the purposes of the antibody comparison initiative, the best antibodies from each manufacturer were selected and compared side-by-side using the same experimental conditions to provide a direct comparison. The antibodies were collected centrally, repackaged and given an internal reference ID prior to delivery to independent laboratories to ensure objective testing and to minimize bias.“””””””
