產(chǎn)品提供形式：

Liquid or Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
緩沖液：

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
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℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
儲存條件：

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
保質(zhì)期：

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
貨期：

Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
注意事項：

Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.

靶點詳情

功能：

In presence of calcium ions, it binds to surfactant phospholipids and contributes to lower the surface tension at the air-liquid interface in the alveoli of the mammalian lung and is essential for normal respiration.
基因功能參考文獻：
1. SP-A1 6A4 and SP-A2 1A5 genetic variants may influence the susceptibility to respiratory distress syndrome in late-preterm infants, independently of the effect of other perinatal factors. PMID: 27835691
2. Significant differences in frequency of occurrence of unfavorable genotypes CC rs1965708, AA rs1059046 of SFTPA2 gene and CC rs1130866 of SFTPB gene in influenza patients in comparison with individuals of the control group were not detected. PMID: 26950992
3. In a Dutch cohort study of unrelated patients with idiopathic or familial interstitial pneumonia genetic analysis of SFTPA2 three new mutations in exon 6 of SFTPA2: N210T, G231R, and N171Y were identified. None were found in the control group. PMID: 26568241
4. Investigated the relationship between SP-A2 and SP-B gene polymorphisms and respiratory distress syndrome in preterm neonates. PMID: 26061924
5. Expression of SFTPA2 mRNA and total SP-A protein was significantly lower in cancer tissue. PMID: 25514367
6. In this study, the loci and haplotypes associated with pulmonary tuberculosis (PTB) were found mostly to be located in the SFTPA2 gene, suggesting that the effects of the SFTPA2 gene on PTB are stronger than those of SFTPA1. PMID: 24984162

11. sequence variability at the 3'UTR of SFTPA1 and SFTPA2 gene variants differentially affects miRNA regulation of gene expression. PMID: 24793167
12. The aim of this report is to describe the genetic complexity of the SFTPA1 and SFTPA2 genes, as well as to review regulatory mechanisms that control SP-A expression in humans and other animal species.[review] PMID: 23069847
13. findings show rs1650232 is in partial linkage disequilibrium with known SP-A2 marker single-nucleotide polymorphisms previously associated with risk for respiratory diseases including tuberculosis PMID: 23328842
14. proteins including the 14-3-3 family bind two cis-elements within exon B of hSP-A2 mRNA in a sequence- and secondary structure-specific manner. PMID: 23525782
15. SP-A2 G231V and F198S mutants impair the dimmer/trimer assembly, which contributes to the protein sialylation and secretion deficiency. The intracellular protein mutants could be partially degraded through the proteasome pathway and formed aggregates PMID: 23056344

25. We conclude that SP-A permeabilizes phospholipid membranes in an LPS-dependent and rough LPS-specific manner, that the effect is neither SP-A- nor species-specific, and that oxidative damage to SP-A abolishes its membrane destabilizing properties PMID: 16489761
26. Residue 85 plays an important role in the structure and function of SP-A and is a major factor for the differences between SP-A1 and SP-A2 variants. PMID: 17580966
