Rabbit Anti Mouse Fibrinogen Polyclonal Fractionated Biotin Labeled 1mg - Rabbit Anti Mouse Fibrinogen Polyclonal Fractionated Biotin Labeled from Innovative Research is a polyclonal antibody in frozen liquid format, buffered in 0.05M Sodium Phosphate; 0.1M NaCl; 1mM EDTA; pH 6.6. This antibody preparation is purified from whole antiserum using protein A affinity chromatography, resulting in the IgG fraction of the antiserum, followed by biotin conjugation. Polyclonal Fractionated preparations may be especially useful in research where high affinity is necessary, especially in cases where the target antigen is less abundant. IgG Fractionated antiserum can also contain very high affinity antibodies that are sometimes missing from affinity purified preparations (since they can bind so tightly to the affinity matrix that they are not always eluted). This product can be used for applications like ELISA, Western Blot.
