重组人白细胞功能相关抗原3融合蛋白(Human LFA-3)

LFA 3 Human
Lymphocyte Function Associated Antigen-3 Human Recombinant , Fusion Protein
Catalog No. CYT-423

Synonyms:
CD58, LFA-3, Ag3, Surface glycoprotein LFA-3.

Introduction:
LFA-3 is ligand of the t-lymphocyte cd2 glycoprotein. This interaction is important in mediating thymocyte interactions with thymic epithelial cells, antigen-independent and dependent interactions of t-lymphocytes with target cells and antigen- presenting cells and the t-lymphocyte rosetting with erythrocytes. In addition, the lfa-3/cd2 interaction may prime response by both the cd2+ and lfa-3+ cells.

Description:
Lymphocyte Function-Associated Antigen-3 Fusion Protein Recombinant Human is produced by recombinant DNA technology in a Chinese Hamster Ovary (CHO) mammalian cell expression system. The molecular weight is 91.4 kilodaltons.
Recombinant LFA3 is purified by proprietary chromatographic techniques.

Source:
Chinese Hamster Ovary

Physical Appearance:
Sterile Filtered White lyophilized (freeze-dried) powder.

Formulation:
Each mg of CD58 contains 0.8mg sucrose, 0.3mg glycine, 0.25mg sodium citrate dihydrate, and 4µg citric acid monohydrate.

Solubility:
It is recommended to reconstitute the lyophilized LFA-3 Human in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

Stability:
Lyophilized LFA3 Human although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Human LFA-3 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.

Purity:
Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Usage:
ProSpec's products are furnished for LABORATORY RESEARCH USE ONLY. They may not be used as drugs,agricultural or pesticidal products, food additives or household chemicals.
