Single-channel and multi-channel micro pipettes, tips.

4 Reagents

4.1 0.01mol/LpH7.2PBS (see Appendix A A.1). 4.2 trypsin solution (see Appendix A A.2). 4.3 0.01mol/LKIO4 solution (see Appendix A in A.3). 4.4 1% glycerol saline (see Appendix A A.4). 4.5 Aschoff (Alsevers) solution (see Appendix A, A.5). 4.6 0.5% chicken erythrocytes (see Appendix A, A.6). 4.7 HI test antigen and positive and negative serum (see Appendix A, A.7). 5 hemagglutination (HA) test 5.1 Using a multichannel micropipette 1 to 12 well microtiter plate were added 0.05mLPBS, exchange tips. 5.2 draw 0.05mL antigen, adding the first hole, repeatedly beaten 3-5 times to mix. 5.3 lessons from the first hole antigen was added 0.05mL second hole, mix draw 0.05mL added the third hole, so to carry out dilution. The first 11 holes from the 11th hole to draw 0.025mL abandoned, for the tip. 12th hole as a red blood cell controls. Each well was added 5.4 0.05mL0.5% (volume fraction) of chicken erythrocytes (red blood cells after adding the chicken Shake). 5.5 Mix gently and let stand at room temperature after 20min observations (20 ℃ ~ 25 ℃) under (if the ambient temperature is too high, it can be placed 4 ℃ environment). RBC control wells significantly determination results were button-like. 5.6 Results found. the reaction plate is inclined 45 °, was not observed if the teardrop-shaped red blood cells flowing, the penalty for HA positive; completely hemagglutinin (not flow Drip) virus dilution highest representative of a hemagglutination units (HAU). 6 hemagglutination inhibition (HI) test 6.1 Procedure 6.1.1 serum samples. a serum sample to be subject to inspection "trypsin - heating - periodate method" treated to remove non-specific serum ......
