PL 7 Human
Threonyl-tRNA Synthetase Human Recombinant
Catalog No. ENZ-304

Synonyms:
Threonyl-tRNA synthetase cytoplasmic, EC 6.1.1.3, Threonine-tRNA ligase, ThrRS, MGC9344, PL-7, TARS.

Introduction:
Threonyl-tRNA Synthetase is a member of the aminoacyl-tRNA synthetase family, key enzymes of protein biosynthesis which charge tRNA molecules with the respective amino acids. This 83 kDa protein is an autoantigen recognized by PL-7 antibodies which occur in a subset of patients with polymyositis and dermatomyositis. Preliminary data suggest that PL-7 antibodies (similar to Jo-1 antibodies) indicate an increased risk for lung involvement, but this needs to be confirmed for a larger number of cases.

Description:
Threonyl-tRNA Synthetase Human Recombinant produced in SF9 is a glycosylated, polypeptide chain having a molecular mass of 83,312 Dalton.
PL-7 is expressed with a -6xHis tag and purified by proprietary chromatographic techniques.

Source:
Sf9 insect cells.

Sterile Filtered clear solution.

Formulation:
PL-7 is supplied in 20mM HEPES buffer pH-8, 200mM sodium chloride, and 20% glycerol.

Immunological functions:
1. Binds IgG-type human auto-antibodies.
2. Standard ELISA test (checker-board analysis of positive/negative sera panels immuno-dot test).

Applications:
Western-Blot with monoclonal anti-hexa-His-tag antibody & Polymyositis sera.
