GRADE & PURITYAnimal Free?Animal-free — produced without animal-derived components to reduce contamination risk. Use in biomanufacturing and culture avoiding animal-origin material.Carrier Free?Carrier-free — supplied without added carrier protein/stabilizer. Use when carriers (e.g. BSA) would interfere with conjugation or sensitive assays.Bioactive?Bioactive grade — verified to retain biological activity in functional assays. Use when the molecule must be functionally active, not just pure.ActiBioPure™?ActiBioPure™ — Aladdin's premier line for bioactive and recombinant products. Use when both high purity and preserved biological activity are required.High Performance?High-performance grade with optimized purity and performance characteristics. Use for sensitive analyses where ordinary grades fall short.His Tag?His tag grade — recombinant protein bearing a His tag for affinity purification/detection. Use to purify, immobilize, or detect the tagged protein.≥90%(SDS-PAGE)

Endotoxin Concentration
<0.1 EU/μg
Bioactivity
Measured by its binding ability in a functional ELISA. When Recombinant Human Cerebellin-2 is coated at 5 μg/mL, biotinylated recombinant rat NRXN-1 beta binds with an apparent KD <1.5 nM. Measured by its ability to enhance neurite outgrowth of E16-E18 rat embryonic cortical neurons. Recombinant Human Cerebellin-2, immobilized at 3-30 μg/mL, is able to significantly enhance neurite outgrowth.

Recombinant Human Cerebellin-2 Protein (rp166920) - SDS-PAGE 2 μg/lane of Recombinant Human Cerebellin-2 Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing a band at 28 kDa under reducing conditions and >120 kDa under non-reducing conditions. Cerebellin-2 protein forms a stable homohexamer through dual-layer disulfide bonding: 1.Trimer formation: Three identical subunits associate via non-covalent interactions of their globular C1q domains and are stabilized by inter-subunit disulfide bonds, constituting a homotrimer. 2.Hexamer assembly: Two trimers connect through disulfide bonds formed by N-terminal cysteine residues, ultimately yielding a covalently linked hexamer. This hierarchical architecture relies on disulfide bonds and C1q domains to ensure protein stability and function (inferred from homologous proteins).
