Form	Liquid or Lyophilized powder
Buffer	Liquid form: default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. Lyophilized powder form: the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution	Briefly centrifuged the vial prior to opening to bring the contents to the bottom. Reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL. It is recommended to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. The default final concentration of glycerol is 50%.
Storage	1. Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. 2. Avoid repeated freeze-thaw cycles. 3. Store working aliquots at 4°C for up to one week. 4. In general, protein in liquid form is stable for up to 6 months at -20°C/-80°C. Protein in lyophilized powder form is stable for up to 12 months at -20°C/-80°C.
Notes	Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Tissue Specificity	Expressed in most tissues, with the highest levels in primary blood Leukocytes and other hematopoietic system tissues, colon, stomach and to some extent in testis.

Gene Functions References

These data uncover a promycobacterial role for STING-dependent OASL production during Mycobacterium leprae infection that directs the host immune response toward a niche that permits survival of the pathogen. PMID: 27190175
OASL acts as a cellular antiviral protein and RSV NS1 suppresses this function to evade cellular innate immunity and allow virus growth. PMID: 26178980
Primary mononuclear cells from patients with systemic sclerosis have increased basal levels of OASL and OAS2 genes. PMID: 24328427
these findings show a mechanism by which human OASL contributes to host antiviral responses by enhancing RIG-I activation. PMID: 24931123
we propose that VSV treatment combined with the selective regulation of genes such as STAT1 and OASL2 will improve therapeutic outcomes for CUG2-overexpressing tumors PMID: 23306614
variants in LPL, OASL and TOMM40/APOE-C1-C2-C4 genes are associated with multiple cardiovascular-related traits PMID: 21943158
The pronounced difference in gene regulation between the OASL gene agrees with a functional difference between these genes, which must exist as a consequence of the lack of the 2-5A synthetase activity of the OASL protein. PMID: 19203244
The expression of OASL and IFIT2 was significantly higher in SLE patients than in controls. PMID: 20506645
OASLa, a major isoform of OASL induced in human liver, may mediate anti-HCV activity through two different domains. PMID: 20074559
interaction with methyl CpG-binding protein 1 was confirmed in vitro and in vivo and was mapped to the ubiquitin-like domain of p59 OASL PMID: 14728690
Proof that OASL is an antiviral protein that works through a novel mechanism distinct from other OASL proteins in other vertebrate species. PMID: 18931074

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
