CD4 - T-cell surface glycoprotein CD4
Order number: 70711
Description
We are excited to introduce our off-the-shelf, full-length, active, and native T-cell surface glycoprotein CD4, which is commonly known as CD4. It is a glycoprotein involved in the immune response and cell-mediated immunity. T lymphocytes that carry the CD4 surface antigen are called T helper cells and are the subtype of T lymphocytes that are primarily infected by HIV. It is therefore a target for HIV infection and immunotherapy.
Our CD4 protein has been solubilized and stabilized using our NativeMP™ platform, ensuring it retains its native structure and full biological activity, making it ideal for various research applications.
