Description

FGFR-1 beta is a member of the FGFR family that interacts with fibroblast growth factors and regulates mitosis and differentiation. It specifically binds acidic and basic fibroblast growth factors and is involved in limb induction. FGFR-1 beta (IIIb) Protein, Human (HEK293, His) is a recombinant protein dimer complex containing human-derived FGFR-1 beta, expressed by HEK293 , with C-His labeled tag. FGFR-1 beta (IIIb) Protein, Human (HEK293, His), has molecular weight of 45-60 kDa.

Background

The FGFR-1 beta protein is a highly conserved member of the fibroblast growth factor receptor (FGFR) family, sharing a similar amino acid sequence with other members. FGFR family members exhibit different affinities for ligands and are distributed across various tissues. The full-length protein consists of an extracellular region with three immunoglobulin-like domains, a hydrophobic membrane-spanning segment, and a cytoplasmic tyrosine kinase domain. The extracellular portion interacts with fibroblast growth factors, initiating downstream signals that regulate mitogenesis and differentiation. FGFR-1 beta specifically binds to both acidic and basic fibroblast growth factors and plays a role in limb induction. Mutations in this gene have been associated with several syndromes and disorders, including Pfeiffer syndrome, Jackson-Weiss syndrome, Antley-Bixler syndrome, osteoglophonic dysplasia, and autosomal dominant Kallmann syndrome 2. Chromosomal aberrations involving this gene are linked to stem cell myeloproliferative disorder and stem cell leukemia lymphoma syndrome. Various alternatively spliced variants encoding different protein isoforms have been identified, although not all variants have been fully characterized. The FGFR-1 beta protein exhibits ubiquitous expression in multiple tissues, including the ovary, fat, and 25 other tissues.

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

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
