HCG-alpha(HCGa/53) , CF488A conjugate , 0.1mg / mL

This MAb reacts with a protein of ~13 kDa , identified as α sub-unit of HCG. HCG is a glycoprotein , which is secreted in large quantities by normal trophoblasts. It is present only in trace amounts in non-pregnant urine and sera but rises sharply during pregnancy. HCG is composed of two non-identical , non-covalently linked polypeptide chains designated as the alpha and beta subunits. The alpha subunit is identical to that of thyroid stimulating hormone (TSH) , follicle stimulating hormone (FSH) , and luteinizing hormone (LH).Primary antibodies are available purified , or with a selection of fluorescent CF® Dyes and other labels. CF® Dyes offer exceptional brightness and photostability. Note: Conjugates of blue fluorescent dyes like CF®405S and CF®405M are not recommended for detecting low abundance targets , because blue dyes have lower fluorescence and can give higher non-specific background than other dye colors.
