General description

FGFR-1 (fibroblast growth factor receptor 1) is a member of the basic fibroblast growth factor family of proteins and is thought to be important in the induction and propagation of benign prostatic hyperplasia. A shortage of FGFR-1 causes death post-implantation and has been linked to neurofascin and neurite outgrowth. FGFR-1 expression has recently been found to be increased in patients with renal cell carcinoma and FGFR-1 may also have a role to play in early limb formation.

Specificity

This antibody recognizes FGFR-1 phosphorylated at Tyr653/Tyr654.

Immunogen

Epitope: Phosphorylated Tyr653/Tyr654
KLH-conjugated linear peptide corresponding to human FGFR-1 phosphorylated at Tyr653/Tyr654.

Application

Detect phospho-FGFR-1 (Tyr653/Tyr654) using this Anti-phospho-FGFR-1 (Tyr653/Tyr654) Antibody validated for use in WB, Cell Function Assay.
Peptide Inhibition Assay Analysis: 0.2 µg/mL from a representative lot peptide blocked in HEK293T cells transfected with FGFR-1.
Research Category
Inflammation & Immunology
Research Sub Category
Cytokines & Cytokine Receptors

Quality

Evaluated by Western Blot in untreated and lambda phosphatase-treated HEK293T cells transfected with FGFR1.

Western Blot Analysis: 0.2 µg/mL of this antibody detected FGFR-1 in 10 µg of untreated and lambda phosphatase-treated HEK293T cells transfected with FGFR1.

Target description

~145 kDa observed.
FGFR-1 has 19 isoforms and eight potential glycosylation sites that increase the expected size to 120 kDa for the immature form and 145 kDa for the mature form of the receptor (Hisaoka, K., et al. (2011). JBC. 286(24):21118-21128).

Physical form

Affinity purified
Purified rabbit polyclonal in buffer containing 0.1 M Tris-Glycine (pH 7.4), 150 mM NaCl with 0.05% sodium azide.

Storage and Stability

Stable for 1 year at 2-8°C from date of receipt.

Analysis Note

Control
Untreated and lambda phosphatase-treated HEK293T cells transfected with FGFR-1
