Human Cluster Of Differentiation 33, Active Protein, Cat#RPU60384
SDS-PAGE
Cluster of Differentiation 33 (CD33), a 67-kDa glycoprotein expressed in several cellular components, including Golgi apparatus; external side of plasma membrane; and peroxisome. Involved in several processes, including negative regulation of cytokine production; negative regulation of monocyte activation; and positive regulation of protein tyrosine phosphatase activity. A functional binding ELISA assay was conducted to detect the interaction of recombinant human CD33 and recombinant mouse CD19. Briefly, CD33 was diluted serially in PBS with 0.01% BSA (pH 7.4). Duplicate samples of 100 μl were then transferred to CD19-coated microtiter wells and incubated for 1h at 37°C. Wells were washed with PBST and incubated for 1h with anti-CD33 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 CD33 and recombinant mouse CD19 was shown, the EC50 for this effect is 1.88 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.
