The lower the pKa, the stronger the acid and the greater its ability to donate protons. The pH depends on the concentration of the solution. This is important because it means a weak acid could actually have a lower pH than a diluted strong acid. For example, concentrated vinegar (acetic ...
The lyophilized antibody is stable at room temperature for at least one month and for greater than a year when kept at -20℃. When reconstituted in sterile pH 7.4 0.01M PBS or diluent of antibody, the antibody is stable for at least six weeks at 2-4 ℃备注: 本产品仅供研究实验使用,不...
Combined with anionic polymer at pH greater than pKa of polymer; simultaneous addition; improved paper filler and short fiber retentionUS20040171719 Feb 27, 2004 Sep 2, 2004 Neivandt David J. Starch compositions and methods of making starch compositions...
储存液:0.01M TBS(pH7.4) with 1% BSA, 0.03% Proclin300 and 50% Glycerol. 保存条件:Store at -20 °C for one year. Avoid repeated freeze/thaw cycles. The lyophilized antibody is stable at room temperature for at least one month and for greater than a year when kept at -20°C. When ...
Why is the buffer capacity maximum when pH = pKa? Buffers In chemistry, a buffer is a solution made up of chemicals that can maintain the pH of the solution even when other acids or bases are added. This means it is able to neutralize small amounts of acids or bases. Buffers play a...
An elevated risk of mortality was observed in individuals with a HCT level below 28%, whereas a HCT greater than 28% was not a risk factor for mortality (hazard ratio = 0.99; 95% confidence interval = 0.97-1.01).The JSON schema will return a series of sentences, one per list entry. ...
The lyophilized antibody is stable at room temperature for at least one month and for greater than a year when kept at -20°C. When reconstituted in sterile pH 7.4 0.01M PBS or diluent of antibody the antibody is stable for at least two weeks at 2-4 °C.标记物:可以提供抗体相对应的...
Similarly, S77E/S83E PRKAR1A was able to inhibit metabolic activity of HEK293T in response to forskolin (Figure 3C) and in normal growth conditions (Figure S2D) to a significantly greater degree than either PRKAR1A or STK25 overexpression alone. In order to confirm that PRKAR1A is ...
The pKavalues for –COOH groups in M and G are 3.38 and 3.65, respectively. This results in precipitation of the soluble polymer below pH 2. However, most of the applications of alginate arise from the fact that it forms insoluble gels/precipitates withdivalentmetal ions, especially Ca2+. Th...
Combination of CalA and FSK produced a dramatically greater responses than those of the individual drugs alone, indicating an additive effect as summarized in the quantification histogram (inset). β-actin was used as loading control. Experiments were repeated at least three times. C HT-29 cells ...
