Details of Functionality | Measured by its binding ability in a functional ELISA. When Human CD38 Antibody
(Catalog #
AF2404)
is immobilized at 1.00 μg/mL (100 µL/well), Biotinylated Recombinant
Human CD38 Fc Chimera Avi-tag binds with an ED50 of 1.00-6.00 ng/mL. Measured by its ability to convert the substrate nicotinamide guanine dinucleotide (NGD+) to cyclic GDP-ribose. Graeff, R.M. et al. (1994) J. Biol. Chem. 269:30260. The specific activity is >700 pmol/min/μg, as measured under the described conditions. |

Transferrin and the blood brain barrier Transferrin, an iron binding protein that facilitates iron uptake in cells, is an integral part of a mechanism that may introduce antibody therapies to the central nervous system. Currently, the brain’s ability to take in antibody therapies i... Read full blog post. |
Multifunctional CD38 CD38 is a 42 kD type II transmembrane glycoprotein that uses nicotinamide adenine dinucleotide (NAD) as a substrate to form cyclic adenosine diphosphate ribose (cADPR). This novel multifunctional ectoenzyme has both cyclase and hydrolase enzymatic act... Read full blog post. |
