SECTM1 Protein, Human, Recombinant (His)

Catalog No. TMPY-02045

Secreted and transmembrane 1 (SECTM1), also known as K12, is a transmembrane and secreted protein with characteristics of a type 1a transmembrane protein of SECTM family. It is found in a perinuclear Golgi-like pattern and thought to be involved in hematopoietic and/or immune system processes. The human K12 protein has been shown to be primarily expressed in spleen, prostate, testis, small intestine, and in peripheral blood leukocytes. The K12 protein is expressed on the cell surface in such small amounts as to preclude detection. Alternatively, it may be that K12 on the cell surface is rapidly cleaved to generate a soluble K12 protein. Immunohistochemical analysis of peripheral blood cells shows that K12 is found in leukocytes of the myeloid lineage, with the strongest staining observed in granulocytes and no detectable expression in lymphocytes. May be involved in thymocyte signaling. It had been suggested a role for thymic microenvironment-produced K12 in regulation of thymocyte signaling and cytokine release, particularly in the setting of thymus pathology where IFN-gamma is upregulated such as myasthenia gravis. In addition, as a putative natural CD7 ligand, SECTM1/K12 may be responsible for the costimulatory role it plays in T cell activation.

Questions

QWhat should I do if the product colors are different after multiple purchases?

AFirst, please confirm the batch number. If it's the same batch, please verify the product's color with our technical specialist. If they are from different batches, the color difference may result from variations in the manufacturing process. Factors such as operations, temperature, and duration during production could influence the color. If you have concerns about a specific batch, please download the corresponding quality inspection report from our official website. We take full responsibility for the quality.

QCan inhibitors be used for animal experiments?

AYes, our inhibitors can be used for animal/in vivo experiments. However, some compounds may not have literature supporting their use in animal experiments. In such cases, we cannot guarantee efficacy.

QWhat is the solubility of the product?

AIt is recommended to check the product description and solubility information on our website first. If corresponding information is not available

QCan PEG400 be used instead of PEG300?

APEG300 has moderate viscosity, which facilitates the dissolution and administration of drugs, while also providing good tolerability without adverse effects on animals. PEG400 can replace PEG300. PEG600 is not very recommended because its melting point is close to room temperature.

QIf the product does not dissolve even when it is below the maximum solubility stated in the instructions, what should I do?

AIt is recommended to utilize some auxiliary dissolution methods, such as heating to 45°C or using sonication to accelerate dissolution.

Biological Activity	Activity testing is in progress. It is theoretically active, but we cannot guarantee it. If you require protein activity, we recommend choosing the eukaryotic expression version first.

Reconstitution	A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information.
Stability & Storage	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
Shipping	In general, Lyophilized powders are shipping with blue ice.
