Commonly used antibodies are monoclonal antibodies and polyclonal antibodies. Monoclonal antibody is an antibody secreted by a B lymphocyte clone, prepared by immunizing animals using cell fusion hybridoma technology. Polyclonal antibodies are immune sera obtained from animal blood after directly immunizing animals with purified antigen, and are a mixture of antibodies produced by multiple B-lymphocyte clones. Other commonly used reagents are: 1. 0.01M (pH7.4) phosphate buffered saline (PBS), used for diluting antibodies and washing slides; 2. Cleaning solution, pure water, for washing slides 3. Polylysine Processing slides to prevent stripping 4. Fixing solution: 4% paraformaldehyde or cold acetone, etc .; 5. 15% ~ 30% sucrose, for tissue dehydration; 6. Gradient alcohol dehydration, xylene transparent, paraffin embedding, Or OCT embedding for frozen section; 7, antigen repair solution: citrate buffer (pH6.0); 8, activator: EDTA or Triton X-100; 9, 1% ~ 10% bovine serum albumin (BSA ) Blocking solution; 10, H2O2, inactivation of endogenous peroxidase; 11, coloring solution: choose according to the enzyme you make, if it is HRP, use DAB, if it is AKP, use NBT / BCIP, immune Fluorescence is not required; 12, 50% buffered glycerol mounting solution.

Atmospheric corrosion resistance, is a very special metal accessories, texture is very tough, but very resistant to corrosion, not like the silver will turn black, it will not be as easy as copper jewelry allergy, but not like alloy jewelry because of lead and toxic, and stainless steel jewelry has always been at room temperature for life to maintain their color. Stainless steel jewelry the same material from the inside to the outside, and through artificial sweat test, its characteristics, completely non-corrosive, and resistant to acid, alkali resistant, not color, not fading, not allergic, no deformation, hard, bright. Complete any side effects on the human body and no harm will not occur green high-grade green jewelry.
