Less than 1.0 EU per μg by the LAL method.
Purity :
>95% as determined by SDS-PAGE.
SDS-PAGE Remark(R&NR) :
Human Fetuin B, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
Formulation :
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH8.0. Normally trehalose is added as protectant before lyophilization. Contact us for customized product form or formulation.
Reconstitution :
Please see Certificate of Analysis for specific instructions. For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.
Storage :
For long term storage, the product should be stored at lyophilized state at -20°C or lower. Please avoid repeated freeze-thaw cycles. This product is stable after storage at:
● -20°C to -70°C for 12 months in lyophilized state;
● -70℃ for 3 months under sterile conditions after reconstitution.
Background :
Fetuin-B (FETUB), a second member of the fetuin family in mammals, is also known as Fetuin-like protein IRL685, 16G2 and Gugu, which is expressed in liver and testis and contains 2 cystatin fetuin-B-type domains. FETUB is a protease inhibitor required for egg fertilization. FETUB is also required to prevent premature zona pellucida hardening before fertilization, probably by inhibiting the protease activity of ASTL, a protease that mediates the cleavage of ZP2 and triggers zona pellucida hardening (By similarity). As a liver-derived plasma protein, FETUB is essential for fertilization.

company information

ACROBiosystems
ACROBiosystems is a leading manufacturer of recombinant proteins and other critical reagents to support the development of target therapeutics, vaccines and diagnostic kits.
Our team has worked tirelessly since the genomic sequence of SARS-CoV-2 was first published, developing a serial of critical reagents to fight COVID-19. Our team has successfully developed a new neutralizing antibody titer serologic assay kit for COVID-19 vaccine evaluation (Cat.No.TAS-K022) which really showed excellent performance.
As the emerging variants may have impacted on the development of the COVID-19 epidemic, our team is also going full steam ahead on developing a collection of spike mutants for the emerging variants of SARS-COV-2. The reagents can be used to evaluate the efficacy of the antibodies and vaccination.
We have also developed an extensive collection of recombinant proteins to support the development for bispecific antibodies, antibody drug conjugates and cell therapies.
