Western Blotting
Proteome Tech提供Western Blotting服务。
利用客户送来的蛋白质样品或者试料提供Western Blotting服务,采用客户送来的一级抗体(Primary antibody)和二级抗体(Secondary antibody)。
如果客户未提供一级抗体或者二级抗体时,由本公司按成本价提供。
Assay Development
本公司拥有研发基于ELISA的诊断方法的丰富经验。本公司研发团队曾研发过针对HBV、HCV、HIV、疟疾与过敏等各种疾病的诊断方法。
ELISA不仅可用作疾病的诊断方法,还可广泛用于蛋白质提炼、稳定性、生物医药品的QC等。按照客户需求和试料特性,可研发direct ELISA、indirect ELISA、sandwich ELISA等各种形态ELISA。
1.研发客户所需形式的assay方法
2.为客户提供明确的技术转让服务
