Biotiny­lat­ed

Spec­i­fi­ca­tions

Tar­get

Spike RBD

Syn­onyms

S pro­tein RBD ; S gly­co­pro­tein RBD ; Spike pro­tein RBD

Acces­sion

P59594

Species

SARS

Exact Sequence

Arg306-Phe527

Mol­e­c­u­lar Weight

The pro­tein has a pre­dict­ed MW of 27.9 kDa. Due to gly­co­sy­la­tion, the pro­tein migrates to 36-46 kDa based on Tris-Bis PAGE result.

Activ­i­ty

Immo­bi­lized SARS Spike RBD, His Tag at 2ug/​ml (100ul/​well) on the plate. Dose response curve for Human ACE2, hFc Tag with the EC50 of 39.0ng/ml deter­mined by ELISA. See test­ing image for detail.

Prod­uct Tag

C-His-Avi

Express Sys­tem

HEK293

Puri­ty

> 95% as deter­mined by Tris-Bis PAGE;> 95% as deter­mined by HPLC

Endo­tox­in

Less than 1EU per ug by the LAL method.

Ship­ping, Recon­sti­tu­tion & Storage

Appear­ance

Lyophilized

Ship­ping Conditions

Shipped at ambi­ent temperature.

For­mu­la­tion

Lyophilized from 0.22um fil­tered solu­tion in PBS (pH 7.4). Nor­mal­ly 5% tre­halose is added as pro­tec­tant before lyophilization.

Recon­sti­tu­tion

Cen­trifuge tubes before open­ing. Recon­sti­tut­ing to a con­cen­tra­tion more than 100 ug/​ml is rec­om­mend­ed. Dis­solve the lyophilized pro­tein in dis­tilled water.

Sta­bil­i­ty & Storage

Recon­sti­tut­ed pro­tein sta­ble at -80°C for 12 months, 4°C for 1 week. Use a man­u­al defrost freez­er and avoid repeat­ed freeze-thaw cycles.
