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	Epidermis-specific type I keratin that plays a key role in skin. Acts as a regulator of innate immunity in response to skin barrier breach: required for some inflammatory checkpoint for the skin barrier maintenance.
Protein Families	Intermediate filament family

Potential roles of KRT16, FAM129A and HKDC1 genes upregulation in adaptive stress responses and pathologies are discussed PMID: 29420561 inflammatory cytokines promoted Nrf2 nuclear translocation in psoriatic epidermis, which led to elevated expression of K6, K16, and K17, thus promoting keratinocyte proliferation and contributing to the pathogenesis of psoriasis. PMID: 28576737 The wider spectrum of KRT16 mutations suggests that changes in codons 125, 127, and 132 are most commonly responsible for PC-1 and that proline substitution mutations at codons 127 or 128 may produce more severe disease PMID: 24357266 analysis of a new p.Leu421Pro (c.1262T>C) mutation in the highly conserved helix termination motif of K16 in a large Spanish family that may have a role in pachyonychia congenita PMID: 24118415 Keratin 16 regulates innate immunity in response to epidermal barrier breach. PMID: 24218583 Data established a seven-gene (AR, ESR2, GATA3, GBX2, KRT16, MMP28 and WNT11) prognostic signature to define a subset of triple-negative breast cancer (TNBC). PMID: 23549873 Patients with p.Asn125Asp and p.Arg127Pro mutations in KRT16 exhibited more severe disease than patients carrying p.Asn125Ser and p.Arg127Cys mutations in terms of age of onset of symptoms, extent of nail involvement, and impact on daily quality of life. PMID: 21160496 Data suggest that an immune response to trichohyalin and K16 may have a role in the pathogenesis of the enigmatic disorder. PMID: 20722389 coinheritance of mutations in KRT16 and filaggrin may aggravate the pachyonychia congenita phenotype PMID: 19785597 disease-associated keratin 16 expression is induced by epidermal growth factor is regulated through cooperation of transcription factors Sp1 and c-Jun PMID: 12954631 K16 expression is observed in non-lesional psoriatic skin and may serve as a marker of preclinical psoriasis. PMID: 15239676 ERK2-mediated C-terminal serine phosphorylation of p300 was a key event in the regulation of EGF-induced keratin 16 expression. PMID: 17623675 DPPIV-expression and enzyme activity, Ki-67 antigen and K16 are significantly upregulated in the centre and inner margin of the psoriatic lesion compared to clinically uninvolved skin and the healthy volunteers skin.

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.
