where can I buy samples of Telomerase enzyme.?

If you are in Europe try Novozime (Netherland)\nIf you are in USA try Genencor \n\nTelomerase is an enzyme that take part in replication mechanism, especial in cancer cells (they do not lose a part of its DNA when the two strands are copied)

Go to your local Ministry of Mines and Energy (government), they have plenty of ore samples and such lying around.

Try going to the manufactures website for coupons...sometimes you can order free samples too. Good Luck

You can get it from Sigma-Aldrich.\nCheck their website for a provider / agent near your location. And probably you will not get it if you are going to use it for some private use.

Looks like you will only get them online and in bulk.  Here is a site which offers a sample.  It might be a way to get just one!

Have you looked at www.shopelvis.com. They are a good source of all licensed EPE items...BTW, you've got GREAT taste!

Try a rough DNA isolation, some things u need are detergent, lemons, and a sample like onion.\n\nSimple diffusion experiments with onions, salt, water, etc..

High-throughput DNA Isolation Protocol \n\nCTAB Method \n\n1.      Add 80 ul 2-mercaptoethanol to 40 ml CTAB buffer (see recipe below) right before use (0.2%) and mix. \n\n2.      Preheat CTAB DNA isolation buffer to 65°C in a water bath. \n\n3.      Grind freeze-dried leaf tissue (~100mg) in a Mixer Mill for 3-5 min at 30 time/sec with one 3mm steel bead in a 1.1 ml  tube strip from Qiagen\n\n4.      Carefully pour beads out of tubes and add 300 ul CTAB buffer into each tube with a multi-channel pipette (if a plate is used, you can leave beads in until the end of work)\n\n5.      Cap the tube strips and label each strip, caps and rack, incubate the samples in 65 °C water bath for 60-80 min, use shipping tape to secure the rack and lid to prevent caps from openning up while inverting the rack to mix samples.\n\n6.      Mix samples every 15 min by inverting rack 5-10 times to make sure plant tissue mixes well with the buffer. Watch for sample leaking from caps. \n\n7.      Take samples out of water bath, briefly spin sample box in a centrifuge for 1 min at 1500 rpm (balance box weight before spinning), separate caps from tube and put the cap strips on clean paper and arrange them in order so that they can be reused. \n\n8.      Add 300 Chl/IAA (25:1) into each tube with a multi-channel pipette, cap tube with original cap strips, put a plastic board between tube cap and rack lid to make sure every strip cap gets the same pressure from the lid, cover the box with lid, secure the lid with shipping tape. Mix the samples by inverting the box slowly for 15 min (Chloroform can create pressure and cause leaks of chloroform, so the tubes have to be tightly capped).\n\n9.      Centrifuge at 5,700 rpm  for 10 min. \n\n10.  Transfer the aqueous phase using a wide-bore pipette tip (about 200ul) into a labeled clean plate (650 ul plate), add 150 ul of cold isopropanol (-20 °C), securely cover the plate with a plate cover (or cap strips) and mix gently by inverting the plate several times to precipitate DNA. \n\n11.  Recover the DNA by centrifuging at 5,700 rpm (6100g) for 10 min. Discard the supernatant immediately by suddenly inverting the plate and dry it briefly on several layers of paper towels by briefly touching the plate on paper towels two to three times on different positions of towel to remove excess liquid. This step should be very quick (a few seconds). Then turn the plate back upright and air-dry samples to remove excess liquid for ~10 min.\n\n12.  Add 500 ul of 70% Ethanol directly to the pellet, cover the plate, and invert it gently several times to wash  for 5 min. \n\n13.  Centrifuge at 5,700 rpm for 8 min, and quickly discard wash buffer as described previously (check DNA pellet in each well to make sure DNA stayed in the bottoms of wells\n\n14.  Air-dry DNA pellet at room temperature for ~20 mins to remove excess liquid.\n\n15.  Re-suspend the DNA pellet in 200 u1 of ddH2O and leave it at 4°C overnight \n\n16.  DNA concentration will be ~100ng /ul and can be determined using either an agarose gel or a spectrophotometer. \n\n \n\n                                                                            CTAB  DNA Isolation Buffer (500 ml) \n\n \n\n2% (w/v) CTAB (sigma)\n 10.0 g\n \n1.4M NaCI\n 40.91 g\n \n20 mM EDTA\n 20 m1 of 0.5 M EDTA \n \n100 mM Tris. HCI (pH 8.0)\n 50 ml of 1.0 M\n \nAdd ddH2O to make a final volume of 500 ml \n \n\n \n\nSDS Method \n\n1.      1-2 young leaves (~100mg) are placed in a labeled 1.1-ml collection tube or in a plate well, freeze-dried, and ground for 3-5 min at 30x/sec to a fine powder using a Mixer Mill and one 3-4mm steel bead in each well. (To isolate DNA from dry seeds, half to 3 seeds are wrapped with a weighing paper, crushed with pliers, placed in a col1ection tube or   in a deep-well plate ).\n\n2.      Preheat extraction buffer to 65°C in a water bath. (If the tissue samples are stored at -20°C, allow them to warm up to room temperature).\n\n3.      Add 0.2% (v/v) ß-mercap
