Human Cubilin, Active Protein, Cat#RPU60608
SDS-PAGE
Cubilin (CUBN) is a 460 kDa intrinsic factor-vitamin B12 receptor protein and it is expressed in kidney and small intestine. CUBN is a component of a multiligand endocytic receptor complex, which plays a role in lipoprotein, vitamin and iron metabolism by facilitating their uptake. Besides CUBN serves as important transporter in several absorptive epithelia, including intestine, renal proximal tubules and embryonic yolk sac and it plays an important role in the development of the peri-implantation embryo through internalization of APOA1 and cholesterol. Thus a functional binding ELISA assay was conducted to detect the interaction of recombinant human CUBN and recombinant mouse APOA1. Briefly, CUBN was diluted serially in PBS with 0.01% BSA (pH 7.4). Duplicate samples of 100 μl were then transferred to APOA1-coated microtiter wells and incubated for 1h at 37°C. Wells were washed with PBST and incubated for 1h with anti-CUBN pAb, then aspirated and washed 3 times. After incubation with HRP labelled secondary antibody for 1h at 37°C, wells were aspirated and washed 5 times. With the addition of substrate solution, wells were incubated 15-25 minutes at 37°C. Finally, add 50 uL stop solution to the wells and read at 450/630 nm immediately. The binding activity of recombinant human CUBN and recombinant mouse APOA1 was shown, the EC50 for this effect is 0.03 ug/mL.

Let customers speak for us

from 218 reviews

We were very pleased with Biomatik’s performance on a custom recombinant protein project earlier this summer. Communication throughout the project was excellent, technical questions were addressed promptly, and the supporting analytical and QC data were clear and comprehensive. The recombinant protein was produced to the requested specifications and delivered on schedule. Based on this experience, we have chosen Biomatik for an additional custom protein production project and would be pleased to work with them again.
