Recombinant Human CSF2 Protein, non-tagged, Biotinylated

• Cat.No.: CSF2-210H
• Product Overview: Biotinylated Human GM-CSF is expressed from HEK293 cells. It contains AA Ala 18 - Glu 144 (Accession # NP_000749.2). The product does not contain any epitope tags.

Specification

• Source: HEK293
• Species: Human
• Predicted N Terminal: Ala 18
• Form: Lyophilized from 0.22 um filtered solution in PBS, pH7.4, 10% trehalose.
• Molecular Mass: The protein has a calculated MW of 14.5 kDa. The protein migrates as 18-28 kDa on a SDS-PAGE gel under reducing condition due to glycosylation.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: >95% as determined by SDS-PAGE.
• Characteristic: The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with biotins using standard chemical labeling method. A standard biotin reagent (13.5 angstroms) is used in this product. The biotin to protein ratio is 1-2 as determined by the HABA assay.
• Stability: Samples are stable for up to twelve months from date of receipt at -70ºC.
• Storage: For long term storage, the product should be stored at lyophilized state at -20ºC or lower. Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at: 4-8ºC for 12 months in lyophilized state; -70ºC for 3 months under sterile conditions after reconstitution.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
