Description
Mix-n-Stain™ CF®770 Antibody Labeling Kit is a near-infrared fluorescent dye that is the brightest fluorescent dye available in its spectrum. Antibody conjugates prepared from CF®770 have by far the best signal-to-noise ratio than antibody conjugates prepared from other spectrally similar dyes.
Mix-n-Stain™ antibody labeling kits are a revolutionary antibody labeling technology that allows you to label your primary antibody with biotin or one of our superior CF® dyes in 30 minutes without the need for a purification step. The labeling procedure tolerates many common buffer components and antibody stabilizers. CF® dyes are highly water soluble, small organic dyes designed for labeling proteins and nucleic acids. Many of our CF® dyes are brighter and more photostable than competing dyes. Click the link for a complete list of more than 20 GoldBio CF® antibody labeling kits.

2110-04-5 | 5 μg | $ 119.00 |
Description
Platelet Factor 4 (PF4) is a non-ELR type of CXC chemokine. PF4 is expressed primarily in megakaryocytes and platelets, but it is also seen in a variety of other cells as well. It is released from alpha granules of activated platelets during platelet aggregation and binds to heparin with high affinity, neutralizing the anticoagulant effect of heparin. Because of this coagulation-promoting activity, it is concluded that PF4 is involved in inflammation and would healing. PF4 binds to the integral membrane protein receptor CXCR3B, an alternatively spliced isoform of CXCR3. It participates in chemotaxis of neutrophils, fibroblasts, and monocytes.

Platelet Factor 4 (PF4) is a non-ELR type of CXC chemokine. PF4 is expressed primarily in megakaryocytes and platelets, but it is also seen in a variety of other cells as well. It is released from alpha granules of activated platelets during platelet aggregation and binds to heparin with high affinity, neutralizing the anticoagulant effect of heparin. Knock-out mice exhibit increased platelets counts and reduced thrombus formation following vascular injury. PF4 binds to the integral membrane protein receptor CXCR3B, an alternatively spliced isoform of CXCR3. PF4 participates in chemotaxis of neutrophils, fibroblasts, and monocytes.

ProBlock™ Gold contains both irreversible and reversible protease inhibitors to inhibit serine, cysteine and other proteases. An separate bottle of EDTA is provided to inhibit metalloproteases.
Since some proteins require divalent cations like Ca2+, Mg2+ or Mn2+ for their biological activity, the presence of EDTA may be detrimental to the protein activity. Furthermore, if the protein of interest is purified using immobilized metal chelate affinity chromatography, EDTA must be removed from the buffer before the chromatography. The ProBlock™ Gold is therefore supplied with a separate, optional EDTA solution which may be added to the extraction buffer or lysate as needed.
