FLT3 Protein, Human (T227M, HEK293, His)

Cat. No.: HY-P75183
SDS COA Handling Instructions

FLT3 is a tyrosine-protein kinase receptor that regulates differentiation, proliferation, and survival of hematopoietic progenitor cells and dendritic cells. It phosphorylates downstream effectors such as SHC1 and AKT1, activating signaling cascades involving MTOR, RAS, and MAP kinases. FLT3 Protein, Human (T227M, HEK293, His) is the recombinant human-derived FLT3 protein, expressed by HEK293 , with C-His labeled tag.

Description

FLT3 is a tyrosine-protein kinase receptor that regulates differentiation, proliferation, and survival of hematopoietic progenitor cells and dendritic cells. It phosphorylates downstream effectors such as SHC1 and AKT1, activating signaling cascades involving MTOR, RAS, and MAP kinases. FLT3 Protein, Human (T227M, HEK293, His) is the recombinant human-derived FLT3 protein, expressed by HEK293 , with C-His labeled tag.

Background

FLT3, a tyrosine-protein kinase, functions as a cell-surface receptor for the cytokine FLT3LG, exerting regulatory control over the differentiation, proliferation, and survival of hematopoietic progenitor cells and dendritic cells. This receptor facilitates the phosphorylation of various downstream effectors, including SHC1 and AKT1, and activates signaling cascades involving MTOR, RAS, MAPK1/ERK2, and/or MAPK3/ERK1. Moreover, it plays a pivotal role in the phosphorylation of FES, FER, PTPN6/SHP, PTPN11/SHP-2, PLCG1, and STAT5A and/or STAT5B. While wild-type FLT3 activation leads to modest STAT5A or STAT5B activation, mutations causing constitutive kinase activity result in heightened cell proliferation and resistance to apoptosis, underscoring its role in fostering aberrant signaling pathways.

Biological Activity

Measured by its binding ability in a functional ELISA. Immobilized Recombinant Human Flt-3 Ligand at 10 μg/mL can bind Human Flt-3. The ED50 for this effect is 0.3422 μg/mL.

Molecular Weight

Approximately 80-110 kDa due to the glycosylation.

Purity
  • Greater than 95% as determined by reducing SDS-PAGE.
Appearance

Lyophilized powder

Formulation

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4, 8% trehalose.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping

Room temperature in continental US; may vary elsewhere.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

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)
× = ×

The specific activity calculator equation

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

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