Immunolocalization of a 22 kDa protein (IPLA7, P22) ofBorrelia burgdorferi

Immunolocalization of a 22 kDa protein (IPLA7, P22) of Borrelia burgdorferi.

The monoclonal antibody LA7 was raised against the species-specific Borrelia burgdorferi lipoprotein P22 (= IPLA7), which induces antibody formation in patients with Lyme arthritis. It is composed of 194 amino acids with a calculated molecular mass of 21.8 kDa. Its gene on the linear chromosome is 582 nucleotides in length. The aim of this study was to localize the protein P22 by immune electro...

Topological studies of spinach 22 kDa protein of Photosystem II.

An intrinsic 22 kDa polypeptide is associated with the O2-evolving Photosystem II core complex in a variety of green plants, although it does not appear to be required for O2 evolution. Digestion of thylakoid membranes and isolated Photosystem II preparations with trypsin, followed by immunoblotting using spinach anti-22 kDa antibodies, leads to two observations: (1) the domain between the 2nd ...

CAV 1 ( caveolin 1 , caveolae protein , 22 kDa )

Immunolocalization of the 150 kDa protein in cyst fluid of Taenia solium metacestodes.

The 150 kDa protein of cyst fluid (CF) of Taenia solium metacestodes was purified by ammonium sulfate fractionation and Superose 6 HR gel filtration chromatography. The purified protein consisted of three subunits (15, 10 and 7 kDa proteins), which were analyzed with the use of a 7.5-15% gradient sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). Immunofluorescence study was ...

Cloning and characterization of a gene encoding 22 kDa functional protein of bacteriophage MB78.

Functional protein of MB78 bacteriophage having apparent molecular weight of 22 kDa is expressed from 1.7 kb HindIII G fragment. The nucleotide sequence of this fragment showed two open reading frames of 222 and 196 codons in tail-to-tail orientation separated by a 62-nucleotide intercistronic region. The ORF of 22 kDa protein is present in opposite orientation, i.e. in the complementary strand...
