Reactions are allowed to proceed for 25 to 30 min at 30° with constant shaking at 900 rpm and then stopped by adding 8 tl of 5 x SDS-PAGE sample buffer, followed by boiling for 5 min. Supernatants are applied to 10% SDS-PAGE, followed by autoradiography or phosphorimaging. [Pg.168]

Wash cells and solubilize pellet in SDS-PAGE sample buffer. [Pg.1011]

Add 50 pil of Elution Buffer to each well, mix on the MTP shaker (or vortex) for 1 min, place on the 96-well magnet for 1 min, and transfer the supernatant (eluate) to a fresh MTP for analysis on SDS-PAGE. SDS-PAGE sample buffer may be used Instead of elution buffer If you require a more concentrated sample for analysis. [Pg.31]

Sample buffer (non-reducing conditions). Mix equal volumes of water R and concentrated SDS-PAGE sample buffer R. [Pg.523]

Adding SDS to a final concentration of 0.05% and then dialyzing versus 1 mM NH4HCO3, 0.05% SDS followed by lyophilization in a Speedvac and reconstitution in SDS PAGE sample buffer. [Pg.144]

Figure 1. Apparent heterogeneity of humanized antibody hAB-1. Ten micrograms of each antibody were mixed with non-reducing or reducing SDS-PAGE sample buffer and boiled for ten minutes prior to electrophoresis. The NOVEX molecular weight markers (MW) are identified by their mass values. Samples Lanes 1,5 pMAB, lanes 2,6 hAB-2 and lanes 3,7 hAB-1. HC and LC correspond to heavy and light chains of antibodies, respectively. Figure 1. Apparent heterogeneity of humanized antibody hAB-1.

Figures. Role of a cysteine residue in autoreduction of hAB-1. hAB-1 (50 (ag) was incubated with either NEM (4 jtg) or lAA (200 Rg) in PBS at room temperature for 10 or 30 minutes. At the end of the incubation period, treated and untreated samples (10 pg) were boiled in non-reducing SDS-PAGE sample buffer and electrophoresed.

Remove a 0.5-mL sample of the culture for SDS-PAGE. Centrifuge for 1 min in a microcentrifuge. Discard the supernatant and resuspend the cell pellet in 75 pL of SDS-PAGE sample buffer. Store at -20° C. [Pg.333]
