    7 Protein Modification Services
  • BS094: APC Conjugation Service

    Highly efficient process is used to conjugate allophycocyanin (APC) to clients' antibodies. The highest possible APC labeling yield and stability is ensured.

  • BP000027-GD1: Recombinant Human VEGF165 (aa 27-191) Protein

    Source: HEK 293 cell-derived.
    The VEGF activity is measured in a cell proliferation assay using human umbilical vein endothelial cells (HUVEC). The ED50 for this effect is typically 1-5 ng/ml.
    Endotoxin: < 1.0 EU per ug of the protein by the LAL method.
    Purity: > 95% by SDS-PAGE under reducing conditions.

  • BS052: HRP Conjugation Service

    1. Highly efficient process to conjugate HRP to clients' proteins and antibodies
    2. Amine-reactive HRP achieves the highest possible conjugation yield and stability
    3. Final product can be stored for at least 12 months at -20 C.
    4. HRP enzyme activity is ~150 units/mg
    5. Fast turnaround time: 3-5 days

  • BS077: Fluorophore Conjugation Service

    1. Highly efficient process to conjugate all commercially available fluorophore to clients' proteins and antibodies
    2. The highest possible conjugation yield and stability
    3. Final product can be stored for at least 12 months at -20 C.
    4. Fast turnaround time: 3-5 days

  • BS076: Biotin Conjugation Service

    1. Highly efficient process to conjugate biotin to clients' peptides, proteins or antibodies
    2. The highest possible conjugation yield and stability
    3. Final product can be stored for at least 12 months at -20 C.
    4. Fast turnaround time: 3-5 days

  • BS054: Magnetic Bead Conjugation Service

    Highly efficient process to conjugate magnetic beads to clients' peptides, proteins, and antibodies: the ratio is 20 ug protein or antibody per mg magnetic microbeads in the conjugation reaction; about 6 ug protein or antibody would be conjugated onto the beads at a concentration of 6 ug antibody per mg magnetic beads.

    Fast turnaround time: 3-5 days.

  • BP000028-GD2: Recombinant Human Long R3-IGF-I Protein

    Source: E. coli-derived.
    The IGF-1 activity is calculated by the dose-dependant proliferation of murine BALBC 3T3 cells. The ED50 for this effect is less than 1 ng/ml, corresponding to a specific activity of 1.0x10^6 IU/mg.
    Purity: > 95% by SDS-PAGE and RP-HPLC.
