SBH 19 Years!The World's Leading Provider of Cytokine Cell-Based Assays

Cytokine Bioassay Services

Our cytokine bioassay capability is the most comprehensive one in the US and it is available for you. We are currently offering 300 bioassays in our two state-of-the-art cell culture facilities. SBH Sciences is pleased to offer to the scientific community a unique service, Cytokine Bioassays including: Proliferation and Neutralization, In Vitro Cytotoxicity, Complement Dependent Cytotoxicity (CDCC), Agonist and Antagonist Screening as well as Cytokine Release Assay. In addition, we are continually developing new assays and would be pleased to add others upon your request. We can assure strict confidentiality and superior execution which will be delivered on a timely basis and cost effective manner. The expected turnover time per assay is less than two weeks, and a written report including methods, results, and conclusions will be issued. SBH Sciences is determined to maintain the highest standards and deliver the highest quality products and services. SBH Sciences welcomes suggestions from researchers and encourage you to communicate with us about your particular research needs.

Most of the bioassays are based on a colorimetric method of measuring cell activity using a non-radioactive substrate. This assay has been proven to be equivalent to the [3H]thymidine incorporated assay (Cell Signaling Applications Guide, Promega Corporation). The compound and the standard (if required) are reconstituted, serial diluted, and incubated with the cells over a 20 to 96 hour period.

BMPs (bone morphogenetic proteins) belong to the large group of growth and differentiation factors from the TGF-beta superfamily. The bioassay of the BMPs is based on measurement of alkaline phosphatase production by ATDC-5 chondrogenic cells.

Innovative Bioassay
During the last 19 years we have built our expertise and currently we are providing the most comprehensive Cell-Based Cytokine assays in the US. Our array of cytokine bioassay services already accelerated discovery and development programs in numerous Biopharmaceuticals companies.    

In addition, we have developed and implemented many NEW assays which become Industry STD. The list below is demonstrating our unique contribution to the Cytokine industry. We are proud to present our innovation and dedication and would be delighted continue assisting the R&D community. Please contact us with any question. Our mission is to be an extension of your research and development team!

Tube Formation Assay
We have developed three bioassays that are based on Tube Formation Assay: h-VEGF-alpha, h-GRO and h-IP-10.

We are currently developing new assays. Click here for more information.

Blood and PBMC-Based Assays
We have developed seven bioassays using PBMC for the analysis of: h-4-1BBL, h-AITRL, h-CD-40 Ligand, h-IL-17B, h-IL-23,h-OX40-Ligand and h-TL-1A/

We are currently developing new assays using Blood cells. Click here for more information.

Custom Bioassay Development
SBH Sciences provides complete custom bioassay development for the Pharmaceutical, Biotechnology and diagnostic industry. Our experience in bioassay development allows us to quickly develop custom assays to fit most applications.

Whenever you need to analyze the activity of novel compounds or neutralization capability of your antibody or receptor, please contact us. SBH Sciences can design, develop and validate the assay to meet your specific requirements.

Our in-vitro bioassays services will assist to assess the mechanism of action for monoclonal antibodies, recombinant proteins, small molecule therapeutics across a range of disease states including cardiovascular, inflammation, immunology, oncology, and CNS disorders.

Please see our current bioassays or contact us so we can discuss your needs, and ways in which SBH Sciences might be able to work with you.

Our mission is to be an extension of your research and development team.

In-Vitro Cytotoxicity Testing
We currently have over 400 mammalian cells with over 350 different human cancer cell lines, as well as numerous Primary human cells (e.g., HEKa, HUVEC, HMVEC, NHDF, NHEK, PBMC). We already perform thousands of anticancer drug testing. We can analyze the biological activity of your compound by itself or in combination with known anticancer drug. See below for a full list of anti-cancer drugs currently available. Click here for more information.
