Exact Sequence

Val40-Ala89

Mol­e­c­u­lar Weight

The pro­tein has a pre­dict­ed MW of 32.9 kDa. Due to gly­co­sy­la­tion, the pro­tein migrates to 38-45 kDa based on Tris-Bis PAGE result.

Activ­i­ty

Immo­bi­lized Human TGF-alpha, hFc Tag at 0.2ug/ml (100ul/​well) on the plate. Dose response curve for Biotiny­lat­ed Anti-TGF-alpha Anti­body, hFc Tag with the EC50 of 12.3ng/ml deter­mined by ELISA (QC Test). The affin­i­ty con­stant of 0.31 uM as deter­mined in SPR assay (Bia­core T200). See test­ing image for detail.

Ship­ping, Recon­sti­tu­tion & Storage

Appear­ance

Lyophilized

Ship­ping Conditions

Shipped at ambi­ent temperature.

For­mu­la­tion

Lyophilized from 0.22um fil­tered solu­tion in 50mM Tris,100mM NaCl (pH 8.0). 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.
