復溶：

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

功能：

Spectrin is the major constituent of the cytoskeletal network underlying the erythrocyte plasma membrane. It associates with band 4.1 and actin to form the cytoskeletal superstructure of the erythrocyte plasma membrane.
基因功能參考文獻：
1. a novel HE case with a His54Pro mutation in the SPTA1 gene was reported. The results suggested that the His54Pro mutation influenced the role of erythrocyte membrane proteins without reducing its level of expression. PMID: 29484404
2. A novel SPTA1 mutation (H54P) was identified in a case of hereditary elliptocytosis. PMID: 28694211
3. The authors show that SUB1-mediated processing of MSP1 is important for parasite viability, the processing modifies the secondary structure of MSP1 and activates its capacity to bind spectrin. PMID: 26468747
4. The authors demonstrate that the initial vacuolar membrane around internalized Babesia divergens is formed from protein and lipid components of the red blood cells plasma membrane, including band 3, glycophorin A and spectrin. PMID: 25628009
