Elabscience Ready-to-Use Antibodies

Recombinant Proteins

Recombinant protein is a manipulated form of protein produced through recombinant DNA technology. By inserting the DNA encoding the protein into bacterial or mammalian cells, we can get quantities of target proteins after amplifying expression and purification. Elabscience® offers a diverse selection of more than 4000 proteins for your research, including cytokines, growth factors, immune checkpoint proteins, CD antigen, FC Receptor, enzymes, hormone, etc.

Featured Data

Annexin V
Detection of Apoptotic Camptothecin-treated Jurkat by Annexin V Staining. 

Jurkat were left untrated (left) or treated with 1 μM Camptothecin treated for 4 h (right) and then stained using Annexin V-APC. The combination of Annexin V(PKSH033460), APC labeled allows for the distinction between apoptotic cells (Annexin V-APC positive) and viable cells (unstained).


The bioactivity of recombinant Human IL-6 Protein (PKSH500018) was measured in a cell proliferation assay using TF-1 human erythroleukemic cells. The ED50 for this effect is 0.27 to 0.81 ng/mL.

Immune Checkpoint Proteins

Immune checkpoints are regulators of the immune activation. They consist of stimulatory and inhibitory pathways that maintain self-tolerance and assist with immune response. Stimulatory Immune checkpoints augment immunological responses against pathogens. On the contrary, inhibitory Immune checkpoints negatively regulate T-cell activation. In cancer, immune checkpoint mechanisms are often activated to suppress the nascent anti-tumor immune response, and PD-1, PD-L1, CTLA-4, CD28, OX40 are hot targets for cancer immunotherapy.
