RFP Antibody

SKU: orb420219

Description

RFP antibody

Images & Validation

• Tested Applications: ELISA, WB
• Dilution range: ELISA: 1:2,000 - 1:10,000, WB: 1:1000-1:10,000
• Reactivity: Other
• Application Notes:
  Polyclonal anti-RFP has been tested by SDS-Page and western blot and is designed to detect RFP and its variants. Optimal titers for applications should be determined by the researcher. Expect a band ~27kDa in Western Blot in the appropriate cell lysate or extract.

Key Properties

• Antibody Type: Primary Antibody
• Host: Goat
• Clonality: Polyclonal
• Isotype: IgG
• Immunogen: The immunogen is a Red Fluorescent Protein (RFP) fusion protein corresponding to the full length amino acid sequence (234aa) derived from the mushroom polyp coral Discosoma.
• Purity: Anti-RFP (GOAT) is an IgG fraction purified from monospecific antiserum by a multi-step process which includes delipidation, salt fractionation and ion exchange chromatography followed by extensive dialysis against the buffer stated above. Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-Goat Serum and purified and partially purified Red Fluorescent Protein (Discosoma). No reaction was observed against Human, Mouse or Rat serum proteins. Expect reactivity against RFP and its variants: mCherry, tdTomato, mBanana, mOrange, mPlum, mOrange and mStrawberry.
• Conjugation: Unconjugated

Storage & Handling

• Storage: Store vial at -20° C or below prior to opening. This vial contains a relatively low volume of reagent (25 µL). To minimize loss of volume dilute 1:10 by adding 225 µL of the buffer stated above directly to the vial. Recap, mix thoroughly and briefly centrifuge to collect the volume at the bottom of the vial. Use this intermediate dilution when calculating final dilutions as recommended below. Store the vial at -20°C or below after dilution. Avoid cycles of freezing and thawing.
• Form/Appearance: Liquid (sterile filtered)
• Buffer/Preservatives: 0.01% (w/v) Sodium Azide
• Concentration: 1 mg/mL
• Dry Ice Shipping: Please note: This product requires shipment on dry ice. A dry ice surcharge will apply.
• Disclaimer: For research use only

Population of CD11b + myeloid progenitor cells differentiate into SMA + stromal cells within tumors and in vitro. (A) Representative image of red fluorescent protein (RFP) + stromal cells in tumor from CCR2-RFP heterozygous SCID mouse. (B) RFP+ SMA + double positive cells within tumor stroma. (C) CD11b + SMA + double positive cells within tumor stroma. (D) CD45 + CD11b + CD34 + myeloid progenitor cells in the mammary gland at 1.5 (n = 5 empty vector (EV), 7 CCL2) and 2.5 weeks (n = 5 EV, 7 CCL2) post-transplantation were quantified by flow cytometry. (E) CD45 + CD11b + CD34 + myeloid progenitor cells in the bone marrow at 1.5 weeks (n = 6 EV, 7 CCL2) and 2.5 weeks (n = 3 mice/group) post-transplantation were quantified by flow cytometry. (F) Representative brightfield image of colony formed by CD45 + CD11b + CD34 + myeloid progenitor cells isolated using fluorescence-activated cell sorting (FACS). (G) Colonies in culture co-stained with SMA and collagen I. Statistical differences determined by Mann–Whitney U test. Magnification bars = 50 µm.
