Recombinant Human CD72 Protein, hFc-tagged, Alexa Fluor 555 conjugated

Specification :
| Description : B-cell differentiation antigen CD72 is also known as Lyb-2. CD72 contains one C-type lectin domain. CD72 is a protein active in the immune system of animals. CD72 consists of two identical halves, each of about 39-43 kD, and is a C-type lectin. Its primarily locus of expression is B-cells, where it appears to mediate aspects of B-cell – T-cell interaction. CD72 plays a role in B-cell proliferation and differentiation. CD72 is a ligand for CD5. | Source : HEK293 | Species : Human | Tag : hFc | Form : Lyophilized | Molecular Mass : The protein has a calculated MW of 54.0 kDa. The protein migrates as 60-66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation. | Protein length : Arg117-Asp359 | N-terminal Sequence Analysis : Arg 117 | Endotoxin : | Purity : > 95 % as determined by SDS-PAGE | Characteristic : Disulfide-linked homodimerLabeled with Alexa Fluor 555 via aminesWith an excitation and emission maximum of 555/565 nm, Alexa Fluor 555 can be efficiently excited using a 543 nm He-Ne laser line and detected under standard TRITC/Cy3 filters. | Storage : 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 50 mM Tris, 100 mM Glycine, pH7.5, 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.
