This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 22.0 kDa. The protein migrates as 35-45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
>90% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

High quality SARS-CoV-2 S protein, S1 protein and human ACE2 protein based on the human cell expression platform of HEK293.
ACROBiosystems has developed a series of homogeneous CD3 proteins with good bioactivity. They are verified as 1:1 heterodimers by nonreductive electrophoresis and MALS as well.
ACRO screened a few different beads and bring this tightly controlled superparamagnetic microspheres to you. This product can be widely applied for immunocapture, bio panning and flow cytometry.
ACROBiosystems has developed a series of kit products using its high-quality SARS-CoV-2 antigen proteins to improve the efficiency of anti-SARS-CoV-2 drugs and vaccines development.
