Recombinant FITC-Labeled Human CD19 Protein, His Tag, Yisheng (CAT#: STEM-CT-0254-ZJF)

The Recombinant FITC-Labeled Human CD19 Protein, His Tag manufactured by Yisheng is suitable for detecting CD19-positive cells in research.
CD19 protein plays a central role in B cell activation and humoral immune responses. It is required for the responsiveness of mature B cells to antigen stimulation, germinal center development, and antibody affinity maturation. CD19 has emerged as a promising therapeutic target for hematologic cancers and solid tumors.

Synonyms: CD19; B4; CVID3; Leu-12; MGC12802
Uniprot No.: P15391-1
Source: FITC-Compatible Human CD19 Protein is expressed from HEK293 Cells with His tag at the C-terminal. It contains Pro20-Lys291.
Molecular Weight: The protein has a predicted MW of 60.1 kDa. Due to glycosylation, the protein migrates to 68-72 kDa based on Tris-Bis PAGE result.
Purity: > 95% as determined by SDS-PAGE and HPLC
Endotoxin: < 1.0 EU per 1μg of the protein by the LAL method.
Formulation: Supplied as 0.22μm filtered solution in PBS (pH 7.4).

Shipped with ice pack.
Stored at -25~-15℃ for 1 year from date of receipt.
2-7 days, 2 ~8 ℃ under sterile conditions after reconstitution.
3 months, -25~-15℃ under sterile conditions after reconstitution.
Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
