Research Area	Cell Biology
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	Non-receptor tyrosine-protein kinase that negatively regulates cell proliferation. Positively regulates PTEN protein stability through phosphorylation of PTEN on 'Tyr-336', which in turn prevents its ubiquitination and degradation, possibly by reducing its binding to NEDD4. May function as a tumor suppressor.
Subcellular Location	Cytoplasm. Nucleus.
Protein Families	Protein kinase superfamily, Tyr protein kinase family, SRC subfamily
Database References	KEGG: mmu:14302 STRING: 10090.ENSMUSP00000019913 UniGene: Mm.332432
Tissue Specificity	Expressed in intestinal tract, fetal and adult islets of Langerhans, kidney, liver and lung.

Gene Functions References

Characterization of mice deficient in the Src family nonreceptor tyrosine kinase Frk/rak. Decreases in the circulating levels of T3 but not T4 are reminiscent of euthyroid sick syndrome, a stress-associated clinical condition PMID: 12077350
The tyrosine kinases Brk/PTK6/Sik, Srm, Frk/Rak/Gtk/Iyk/Bsk, and Src42A/Dsrc41 have a low degree of sequence homology to other known kinases. The exon structure of these kinases, called the Brk family, is highly conserved and distinct. PMID: 12725532
Experiments with Fyn-deficient mice indicate that Fyn genotype does not influence ethanol consumption, neither under basal conditions nor following a deprivation period or stress. PMID: 12966312
These results show that FRK affects beta cell number during embryogenesis and early in life, but is probably redundant for beta cell number and function in adult animals under normal conditions. PMID: 17416457

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.
