Database References	HGNC: 13902 OMIM: 603357 KEGG: hsa:8710 STRING: 9606.ENSP00000337212 UniGene: PMID: 28211129 Direct sequencing of SERPINB7 revealed five homozygous founder mutations (c.796C>T) and four compound heterozygous mutations in nine patients, including one novel mutation (c.122_127delTGGTCC). PMID: 27666198 Case Report: striate palmoplantar keratoderma showing transgrediens in a patient with heterozygote nonsense mutations in DSG1 and SERPINB7. PMID: 27786350 Results show splice variants from the two recurrent splice-site mutations in SERPINB7, provide evidence for the pathogenicity of the mutations and suggest an in-frame deletion of exon 3 may cause NPPK and that the CD-loop could affect SERPINB7 function PMID: 25940237 These results indicate that megsin gene variants may play a role in the severity, development, and/or progression of IgAN in Northwest Chinese population PMID: 26871801 Recessive missense mutation of SERPINB7 gene was found in Japanese families diagnosed with palmoplantar keratosis. PMID: 26763456 Megsin 2093C/T TT genotype, and C25663G G allele and GG genotype were associated with the risk of IgAN in Asian population PMID: 25007157 These data clearly provide further evidence that NPPK is caused by loss-of-function mutations in SERPINB7. PMID: 24773080 megsin 2093C/T C allele may be genetic marker for IgA nephropathy susceptibility [review] PMID: 24575807 The mean concentration of serpin B7 at 28-32 weeks was 1.5-fold higher in women with subsequent preterm deliveries compared to controls. PMID: 24954659 study reports on seven unrelated Chinese patients with Nagashima-Type Palmoplantar Keratosis with four underlying SERPINB7 mutations, of which one is a recurrent variant (c.796C>T) PMID: 24514002 All of the identified mutants are predicted to cause premature termination upstream of the reactive site, which inhibits the proteases, suggesting a complete loss of the protease inhibitory activity of SERPINB7 in palmoplantar keratosis skin. PMID: 24207119 A267G in 5'-untranslated region within the exon of megsin may be one of the substantial genetic basis for differentiating "deficiency of liver yin and kidney yin" syndrome and "deficiency of qi and yin" syndrome in primary immunoglobulin A nephropathy. PMID: 18471408 Mesangial cell-predominant gene, megsin. Genetic manipulation of megsin engenders two elementary mesangial lesions, mesangial expansion and an increase in the number of mesangial cells. PMID: 12386281 One positive regulatory motif, an incomplete activator protein-1 binding motif (CTGATTCAC) within the -120 to -112 region. This cis-acting element in the 5'-flanking region of megsin is involved in the activation of the megsin gene in mesangial cells. PMID: 12397041 Megsin has a role in susceptibility to immunoglobulin A nephropathy PMID: 15213261 in transgenic rats, overexpression of human megsin, a recently discovered serpin located in the kidney, produces renal and pancreatic lesions characteristic of serpinopathies PMID: 15788472 In this Chinese population, the 2093C-2180T haplotype at the 3'UTR of MEGSIN gene is associated with more severe forms of IgA nephropathy, and more rapid disease progression PMID: 16431886 The polymorphism of megsin A23167G is associated with susceptibility and progression of IgA nephropathy in Chinese population. GG genotype is associated with severe histological lesions and progression of the disease. PMID: 16550745 study found out that the megsin TT haplotype (defined as T-2093, T-2180 alleles) could play a protective role in the progression of IgA nephropathy PMID: 18498720 recombinant megsin did not affect the mRNA expressions of TGF- and PAI-1, and did not modify the enzymatic activity of PAI-1 PMID: 18580857 Megsin 2093T-2180C haplotype at the 3' untranslated region is associated with poor renal survival in Korean IgA nephropathy patients.

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.
