Cd28-4008MF
Optional Service: Optional requirements on this protein
Product Overview :
FITC conjugated recombinant Mouse Cd28 (Asn20-Lys149) protein was fused to His-tag at C-terminus and expressed in human 293 cells (HEK293).
Description :
T-cell-specific surface glycoprotein CD28 is also known as TP44, is a single-pass type I membrane protein which contains one Ig-like V-type (immunoglobulin-like) domain. is one of the molecules expressed on T cells that provide co-stimulatory signals, which are required for T cell activation. CD28 is the receptor for CD80 (B7.1) and CD86 (B7.2). When activated by Toll-like receptor ligands, the CD80 expression is upregulated in antigen presenting cells (APCs). The CD86 expression on antigen presenting cells is constitutive. CD28 is the only B7 receptor constitutively expressed on naive T cells.
Source :
HEK293
Species :
Mouse
Tag :
His
Form :
Lyophilized
Molecular Mass :
The protein has a calculated MW of 16.9 kDa. The protein migrates as 30-35 kDa and 55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower. Please avoid repeated freeze-thaw cycles. This product is stable after storage at: -20 to -70 centigrade for 12 months in lyophilized state; -70 centigrade for 3 months under sterile conditions after reconstitution.
Storage Buffer :
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4, 10% trehalose.
Reconstitution :
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 μg/μL. Centrifuge the vial at 4 centigrade before opening to recover the entire contents.
