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.

Target Details

Target Function	Required for normal accumulation and movement of lipid-modified hedgehog (hh) morphogen. May act by stabilizing the interaction between heparan sulfate proteoglycans (HSPGs) and hh, HSPGs being required for diffusion of hh morphogen. Not involved in wingless (wg) morphogen movement, suggesting that it may provide HSPG specificity for Hh.
Subcellular Location	Secreted, extracellular space, extracellular matrix. Note=Colocalizes with HSPG.
Database References	KEGG: dme:Dmel_CG3135 STRING: 7227.FBpp0070939 UniGene: Dm.58
Tissue Specificity	At the blastoderm stage, it is ubiquitously expressed. As embryogenesis continues, it is expressed in the epidermis and central nervous system, this expression being segmentally modulated. Also highly expressed at the foregut and hindgut throughout embryo

Gene Functions References

We show that production of this PGC attractant depends upon shf as well as a second hh pathway gene g gamma1. PMID: 24068944
study concludes that the WIF domain is responsible for the divergence between Drosophila Shf and human Wif-1, channeling the recognition either toward Hh or Wg signal, whereas the EGF repeats give the protein the ability to interact with glypicans PMID: 22951645
Shf is the ortholog of the human Wnt inhibitory factor (WIF), a secreted antagonist of the Wingless pathway. Shf is required for Hh stability and for lipid-modified Hh diffusion. PMID: 15691765
Shifted is a secreted protein that acts over a long distance and is required for the normal accumulation of Hh protein and its movement in the wing. PMID: 15691766

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.
