Anti-QRSL1 Antibody

QRSL1 (Glutaminyl-tRNA Synthetase Like 1) is a mitochondrial enzyme that contributes to mitochondrial translation by supporting glutamine-tRNA biosynthesis through an indirect aminoacylation pathway. The Antibodies.com rabbit polyclonal reagent raised against this target is supplied as a 100 µL aliquot of unconjugated IgG, suitable for Western blot detection of endogenous QRSL1 in human and mouse samples.

Because QRSL1 localizes to the mitochondrion, this antibody is frequently used in studies of respiratory chain assembly, oxidative phosphorylation, and broader mitochondrial gene expression. Researchers applying it to cell lysates and tissue extracts can leverage the polyclonal format for recognition of multiple epitopes on the target protein, which is useful when probing low-abundance mitochondrial translation components across different experimental conditions.

Validated reactivity with human and mouse samples makes this reagent a practical choice for cross-species comparative work in mammalian cell biology, including investigations into mitochondrial disorders and metabolic dysfunction. Store the vial refrigerated between uses and minimize freeze-thaw cycles to preserve antibody activity across multiple experiments.
