Accelerate Protein & Antibody Discovery
BioCrest Sci provides end-to-end recombinant protein and antibody CRO services — from target to validation, delivering high-purity, bioactive proteins and custom solutions to empower research, pharma, and diagnostics.
Our Protein & Antibody Products
High purity, bioactivity-validated, covering discovery to validation workflows
Protein
We offer natural, active, and recombinant proteins. In particular, we have over 12,000 recombinant proteins and 750+ active proteins. As a result, you get the
quality and variety you need.
Antibody
Our portfolio covers polyclonal, monoclonal, and recombinant antibodies. Furthermore, we provide antibody pairs and labeled controls. As a result, all products
ensure consistent, reproducible results.
Kits
Our kits streamline ELISA, exosome isolation, and apoptosis detection.
They are easy to use and accurate. Therefore, you get reliable data
faster with less hands-on time.
Active Protein
We provide active proteins with verified bioactivity. Each batch undergoes
strict quality control. As a result, you get consistent purity and
stability for your assays.
Our Protein & Antibody CRO Services
Protein Expression Service
We help you obtain high-yield, functional proteins. In addition, we offer flexible scales from lab to production. Therefore, you get fast turnaround and consistent quality.
Custom Antibody Service
We generate high-affinity antibodies for your specific antigens. Moreover, our service covers immunization, screening, and purification. As a result, you save months of in-house effort.
Single B Cell Screening Service
We isolate antigen-specific antibody sequences directly. Furthermore, this preserves native heavy-light chain
pairing. Therefore, it reduces your lead time significantly.
Custom Nanobody Service
We deliver small, stable, high-specificity nanobodies. In addition, we target challenging proteins like GPCRs
and ion channels. Therefore, you get rapid hit identification and strong expression.
Phage Display Service
We screen billions of peptide and antibody variants. Our service combines
library diversity with proven protocols. Therefore, you identify
high-affinity binders efficiently.
Stable Cell Line Production
We provide high-titer, long-term protein and antibody production. We
prioritize clonal selection and regulatory documentation. As a result,
your project scales from R&D to commercial needs.
