Description	TMEFF1/Tomoregulin-1 protein may inhibit NODAL and BMP signaling in neural patterning, suggesting a regulatory role in neural development. It has been proposed as a tumor suppressor in brain cancer, emphasizing its importance in mitigating abnormal cell growth. TMEFF1/Tomoregulin-1 Protein, Human (HEK293, Fc) is the recombinant human-derived TMEFF1/Tomoregulin-1 protein, expressed by HEK293 , with C-hFc labeled tag. The total length of TMEFF1/Tomoregulin-1 Protein, Human (HEK293, Fc) is 291 a.a., with molecular weight of ~65 kDa.
Background	The TMEFF1/Tomoregulin-1 protein is implicated in potentially inhibiting NODAL and BMP signaling during neural patterning, suggesting its role in the regulatory processes governing neural development. Furthermore, TMEFF1 is proposed to function as a tumor suppressor in brain cancers, underscoring its potential significance in mitigating abnormal cell growth in neural tissues. Additionally, the protein may interact with ST14, implying a molecular association that may contribute to its regulatory and signaling functions. The multifaceted roles of TMEFF1 highlight its importance in both normal developmental processes and its potential involvement in pathological conditions such as brain cancers.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?
1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss. 2. Taking 10 μg as an example, first add 20 μL of reconstituted solution provided by MCE and use a pipette to gently resuspend the lyophilized protein until it is fully dissolved.. (For most proteins, the reconstitution solution we provide is sterile water. If a diluent other than water is required, it will be indicated in the product's Certificate of Analysis (COA).). 3. Add an additional 80 μL of buffer/culture medium containing carrier protein (either 0.1% BSA, 5% HSA, 10% FBS, or 5% trehalose), and then use a pipette to gently mix until uniform. The final concentration is should not be lower than 100 μg/mL. 4. Aliquot at least 20 μL per tube. 5. After aliquoting, store it frozen at a temperature ranging from -20ºC to -80ºC, and it can be preserved for 3 to 6 months.
How should solution-form recombinant proteins be stored?
1. The product can be stored in its original form and diluted as needed upon use. 2. Alternatively, dilute with a buffer/culture medium containing a carrier protein (either 0.1% BSA, 5% HSA, 10% FBS, or 5% alginate), mix well by pipetting, and ensure that
Why is it necessary to add carrier proteins?
Carrier proteins are commonly added to enhance the stability of recombinant proteins, preventing them from adhering to the walls of the container during freezing or thawing processes. Plastic tubes have a certain adsorptive capacity for proteins, which may lead to difficulty in separating the protein from the tube walls, resulting in a decrease in the actual concentration of the protein in the solution and thus affecting its activity. To minimize such losses, it is recommended to add a commonly used carrier protein solution prior to the long-term storage of recombinant protein products.
Carrier protein types and options?
In cases where the carrier protein is not expected to influence the experimental outcomes, an appropriate carrier protein, such as 0.1% BSA (Bovine Serum Albumin), 5% HSA (Human Serum Albumin), 10% FBS (Fetal Bovine Serum), or 5% trehalose, can be incorpo
