  • De novo antibody sequencing to obtain the intact amino acid sequence of variable and/or constant regions of monoclonal antibodies by LC-MS/MS.

    Sample requirement: 3-5 mg at 1 mg/ml preferred (minimum: 2 mg at 1 mg/mL).

    Fast turnaround time: 2-3 months per antibody, but may require more time depending on the complexity of analysis.

  • 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.

  • 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.

  • - Reliable results. Through development of genome-wide qPCR primers, we have successfully tested over 30,000 genes in qPCR assays. Relative and absolute analysis of gene expression by qPCR is available for all known genes in any organism.
    - Save money. No need to buy real-time PCR instruments or reagents. Our reverse transcription and qPCR reagents are used to save clients' cost.

  • BS093: Anti-SARS-CoV-2 Nucleocapsid Protein (N Protein) Recombinant Rabbit Monoclonal Antibodies

    High sensitivity: the affinity to the SARS-CoV-2 Nucleocapsid protein measured by the Biacore method is as low as 5 pM.

    Antibody pairing: the recombinant rabbit mAbs bind to various epitopes of the SARS-CoV-2 Nucleocapsid protein.

    We have sold recombinant rabbit monoclonal antibodies and licensed some clones to diagnostic companies to develop COVID-19 antigen test kits.

  • BS092: SARS-CoV-2 Specific Human Neutralizing Monoclonal Antibody Development Service

    If clients can provide PBMC from recovered patients or people with vaccines, we do single B cell sorting and culturing. About 70 ul supernatant per well (clonal single B cell) is sent to clients for quick screening. Then we sequence the antibody VH/VL from single B cell clones selected by clients and produce recombinant rabbit single B cell for confirmation.
