Anti-EF1α Antibody, clone CBP-KK1

产品说明

一般描述

Human eukaryotic translation elongation factor 1 alpha has two isoforms, alpha 1 and alpha 2. The alpha 1 isoform gene encodes a subunit of the elongation factor-1 complex which is responsible for the enzymatic delivery of aminoacyl tRNAs to the ribosome. The alpha 1 isoform is expressed in brain, placenta, lung, liver, kidney, and pancreas. The other isoform (alpha 2) is expressed in brain, heart and skeletal muscle.
The alpha 1 isoform is identified as an autoantigen in 66% of patients with Felty syndrome. The gene for the alpha 1 isoform has been found to have multiple copies on many chromosomes, some of which, if not all, represent different pseudogenes. The gene for the alpha 2 may be critical in the development of ovarian cancer.

特异性

This antibody recognizes EF-1α (Elongation factor-1 alpha), Mr 53 kDa. Occasionally, a 38 kDa protein is also detected in A431 cell lysate.

免疫原

RNA Binding Protein (RBP)
Detect EF1α using this Anti-EF1α Antibody, clone CBP-KK1 validated for use in IP & WB.

质量

Routinely evaluated on RIPA lysates from non-stimulated A431 cells, human Jurkat or mouse 3T3/A31.
Western Blot Analysis:
0.5-2 µg/mL of this lot detected EF1α in RIPA lysates from non-stimulated A431 cells. Previous lots detected EF1α in human Jurkat and mouse 3T3/A31 RIPA cell lysates.

外形

Protein G Chromatography
Purified mouse monoclonal IgG1κ in buffer containing 0.1 M Tris-glycine, pH 7.4, 0.15 M NaCl with 0.05% sodium azide.
Format: Purified

储存及稳定性

Stable for 1 year at -20°C from date of receipt.
Handling Recommendations:
Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20ºC. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.

分析说明

Control
Jurkat cell lysate.
Included Positive Antigen Control: Catalog # 12-301, non-stimulated A431 cell lysate. Add 2.5 µL of 2-mercaptoethanol per 100 µL of lysate and boil for 5 minutes to reduce the preparation. Use 20 µg per lane for minigels.

其他说明

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
