Recombinant Human CD48 Protein, His-tagged, Alexa Fluor 555 conjugated

• Cat.No.: CD48-654HAF555
• Product Overview: Alexa Fluor 555 conjugated recombinant human CD48 (Gln27-Ser220) protein was fused to His-tag at C-terminus and expressed in human 293 cells (HEK293).

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: Gln27-Ser220
• Description: CD48 antigen is also known as Signaling lymphocytic activation molecule 2, SLAM family member 2 (SLAMF2), Leukocyte antigen MEM-102, BCM1 surface antigen, B-lymphocyte activation marker BLAST-1. CD48 is a 65 kDa GPI-linked protein which belongs to the CD2 subfamily of immunoglobulin superfamily molecules. CD48 antigen contains two Ig-like C2-type (immunoglobulin-like) domains and two Ig-like V-type (immunoglobulin-like) domain. CD48 interacts with CD244 in an heterophilic manner. CD48 is ligand for CD2. CD48 might facilitate interaction between activated lymphocytes. CD48 is probably involved in regulating T-cell activation.
• Form: Lyophilized
• Molecular Mass: The protein has a calculated MW of 23.2 kDa. The protein migrates as 35-45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• N-terminal Sequence Analysis: Gln 27
• Endotoxin: < 1.0 EU/ μg by the LAL method.
• Purity: > 95 % as determined by SDS-PAGE
• Characteristic: Disulfide-linked homodimer
  Labeled with Alexa Fluor 555 via amines
  With 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 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.
