Background Information

TLR4, also named as CD284, belongs to the Toll-like receptor family. TLR4 interacts with LY96 and CD14 to mediate the innate immune response to bacterial lipopolysaccharide (LPS). TLR4 acts via MYD88, TIRAP and TRAF6, leading to NF-kB activation, cytokine secretion and the inflammatory response. Three alternatively spliced transcript variants that encode different protein isoforms have been described. The calculated molecular weights of the three TLR4 isoforms are 96, 91, and 73 kDa.

B cells (mouse) were lysated in RIPA buffer with protein and phosphatase inhibitors. 10 µg of protein per lane were loaded in a 10% PAGE-SDS gel. Proteins were transferred to a PVFD membrane (Turbo Blot system) and incubated overnight with 1:1000 of anti-TLR4, followed by anti-rabbit-HRP (1:10.000) on the next day. Two bands of around 70 kDa are detected.
