Function
Lumican, also known as LUM, is an extracellular matrix protein that, in humans, is encoded by the LUM gene on chromosome 12. Lumican is a major keratan sulfate proteoglycan of the cornea but is ubiquitously distributed in most mesenchymal tissues throughout the body. Lumican is involved in collagen fibril organization and circumferential growth, corneal transparency, and epithelial cell migration and tissue repair. Corneal transparency is possible due to the exact alignment of collagen fibers by lumican (and keratocan) in the intrafibrillar space.

Sandwich ELISA analysis of Human Lumican matched pair antibodies
Capture: HA725317, Human Lumican Rabbit mAb [PSH19-04] Detector: HA725318, Human Lumican Rabbit mAb [PSH19-05]
Elisa assay was performed by coating wells of a 96-well plate with 100 µl per well of capture antibody (HA725317) diluted in carbonate/bicarbonate buffer, at a concentration of 2 µg/mL overnight at 4℃. Wells of the plate were washed, blocked with 150 µl 0.05% tween-20 1% BSA blocking buffer, and incubated with serial diluted Recombinant Human Lumican protein (HA211171) starting from 80,000pg/ml to 0 pg/ml and detect antibody (HA725318, HRP, 0.05 µg/ml) for 1 hour at 30℃ with shaking. Detection was performed using an Ultra TMB Substrate for 10 minutes at room temperature in the dark. The reaction was stopped with sulfuric acid and absorbances were read on a spectrophotometer at 450 nm.
