Apolipoprotein (apo)H (also known as beta 2 glycoprotein-I) is a glycoprotein synthesized by liver cells and it is present in the blood associated with plasma lipoproteins. APOH displays a genetically determined structural polymorphism: three alleles (APOH*1, APOH*2, APOH*3) at a single locus on chromosome 17 code for different isoforms, and population studies have shown that APOH*2 is the most frequent allele.

Species | Cynomolgus |
Expression System | HEK293 Cells |
Tag | C-His |
Accession Number | XP_045230479.1 |
Synonyms | β(2)GPI,BG,beta(2)GPI,B2GPI,B2GP1,B2G1,Apo-H,APOH |
Construction | Gly20-Cys345 |
Protein Purity | > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC |
Molecular Weight | 37.39 kDa (predicted). Due to glycosylation, the protein migrates to 50-65 kDa based on Tris-Bis PAGE result. |
Endotoxin | < 1 EU/μg by the LAL method. |
Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS, 100 mM Arginine (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization. |
Reconstitution | Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing. |
Stability & Storage | It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
Shipping | In general, Lyophilized powders are shipping with blue ice. |
