RFP-Tag (Ads. to Hu, Ms, Rt Serum Proteins) Rabbit Polyclonal Antibody

Specifications

Product Data
Applications	ELISA, IF, IHC, WB
Recommend Dilution	Antibodies to RFP (Discosoma spp.) are intended for use in immunological assays including ELISA, Western blotting, Fluorometry and Fluorescence Activated Cell Sorting (FACS). Polyclonal anti-RFP is designed to detect RFP and its variants. This antibody can be used to detect RFP by ELISA (Sandwich or Capture) for the direct binding of antigen. Biotin conjugated polyclonal anti-RFP used in a sandwich ELISA with unconjugated anti-RFP is well suited to titrate RFP in solution. The detection antibody conjugated to Biotin is subsequently reacted with streptavidin conjugated HRP. Fluorochrome conjugated polyclonal anti-RFP can be used to detect RFP by Immunofluorescence microscopy in cell expression systems and can detect RFP containing inserts. Significant amplification of signal is achieved using fluorochrome conjugated polyclonal anti-RFP relative to the fluorescence of RFP alone. For Immunoblotting use either Alkaline Phosphatase or Peroxidase conjugated polyclonal anti-RFP to detect RFP or RFP containing proteins on Western blots. Recommended Dilutions: ELISA: 1/20,000-1/50,000. Immunofluorescence: 1/200-1/2,000. Western blot: 1/1,000-1/5,000. Immunohistochemistry: 1/200-1/2,000.
Host	Rabbit
Clonality	Polyclonal
Immunogen	Red Fluorescent Protein (RFP) fusion protein corresponding to the full length amino acid sequence (234aa) derived from the mushroom polyp coral Discosoma
Specificity	Polyclonal anti-RFP is designed to detect RFP and its variants. Assay by Immunoelectrophoresis resulted in a single precipitin arc against anti-Rabbit Serum and purified and partially purified Red Fluorescent Protein (Discosoma). No reaction was observed against Human, Mouse or Rat serum proteins. ELISA was used to confirm specificity at less than 0.1% of target signal. Expect reactivity against RFP and its variants: mCherry, tdTomato, mBanana, mOrange, mPlum, mOrange and mStrawberry.

Concentration	lot specific
Purification	Immunoaffinity Chromatography using Red Fluorescent Protein (Discosoma) coupled to agarose beads followed by solid phase adsorption(s) to remove any unwanted reactivities
Conjugation	Unconjugated
Storage Condition	Store undiluted at 2-8°C for one month or (in aliquots) at -20°C for longer. Dilute only prior to immediate use. Centrifuge product if not completely clear after standing at room temperature. Avoid repeated freezing and thawing.
Database Link	UniProt ID Q9U6Y8
Background	Epitope tagging is a powerful and versatile strategy for detecting and purifying proteins expressed by cloned genes. To utilize this feature, protein expression vectors are typically engineered with a nucleotide sequence that encodes the peptide epitope tag. The gene of interest is cloned in-frame relative to the tag and, upon expression, the protein of interest is synthesized as a fusion protein with the peptide tag. Fusion protein detection and/or purification is mediated by highly specific antibodies to the engineered peptide, thus eliminating the need for antibodies to proteins from each newly cloned gene. Commonly used epitope tags include glutathione-S-transferase (GST), c-myc, 6-histidine (6X-His), FLAG, green fluorescent protein (GFP), red fluorescent protein (RFP, DSRed), maltose binding protein (MBP), influenza A virus haemagglutinin (HA), b-galactosidase, and GAL4.
Synonyms	Red fluorescent protein Tag, DsRed Tag
