Exact Sequence

Glu21-Phe141

Mol­e­c­u­lar Weight

The pro­tein has a pre­dict­ed MW of 40.45 kDa. Due to gly­co­sy­la­tion, the pro­tein migrates to 55-65 kDa based on Tris-Bis PAGE result.

Activ­i­ty

The affin­i­ty con­stant of 25.59 nM as deter­mined in SPR assay (Bia­core T200). See test­ing image for detail.

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 8% 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.
