Protein Labeling Reagents
Enzo Life Sciences Fluorescein-5-maleimide (ultra pure) (25mg). CAS: 75350-46-8
Fluorescein-5-maleimide enables protein labeling via thiol modifications in most proteins at cysteine residues that either are intrinsically present or resulted from reduction of cystine residues. Unlike iodoacetamides, maleimides do not react with histidine and methionine under physiological conditions. The probe is suitable for assessing conformation- dependent accessibility of cysteine residues in proteins. Wavelength Maxima: Excitation 493nm, Emission 515nm Purity: ≥95% (HPLC). Solubility: Soluble in DMSO. Long Term Storage: -20°C.
Enzo Life Sciences AMPIGENE qPCR 1-Step Probe Kit Lo-ROX (200Reactions)
AMPIGENE qPCR 1-Step Probe Kits use the latest developments in reverse transcriptase (RTase) technology and buffer chemistry for efficient cDNA synthesis and qPCR in a single tube. The modified MMLV RTase is blended with RNase inhibitor to prevent degradation of RNA by contaminating RNase. The RTase is thermostable and extremely active. AMPIGENE qPCR 1-Step Probe Kits are designed for use on a variety of probes including: Taqman, Molecular Beacons, and Scorpion probes. An optimized buffer system allows efficient amplification and proprietary enhancers prevent the formation of primers/dimers to increase sensitivity and specificity. ROX is a reference dye which is used to normalize fluorescent signal in qPCR. AMPIGENE qPCR 1-Step Probe Kits come with either Lo-ROX, Hi-ROX, or No-ROX concentration. Choose the appropriate ROX concentration for the instrument (see instrument compatibility for reference dye chart below.) Applications: PCR.
