簡要描述：BD Purified Rat Anti-Mouse CD16/CD32 553141，BD 553141 Pharmingen 純化大鼠抗小鼠 CD16/CD32 抗體，常用于流式細(xì)胞術(shù)和免疫組織化學(xué)等實驗中，作為 BD Fc 阻滯劑。該抗體通過阻斷小鼠 Fc 受體（CD16/CD32）與 Fc 區(qū)域結(jié)合，防止非特異性結(jié)合，從而提高下游實驗中抗體標(biāo)記的特異性和準(zhǔn)確性。

推薦的實驗流程

To specifically stain cells bearing FcγII and FcγIII receptors for flow cytometric analysis: Incubate cell suspension with this antibody (≤ 1 μg/million cells) followed by an appropriate fluorochrome-conjugated second-step reagent.

To reduce Fc receptor-mediated binding by antibodies of interest or Fc receptor-mediated binding by PE-CY5 tandem dye conjugates to FcγII and FcγIII receptor-bearing mouse cells for flow cytometric analysis:

1. Preincubate cell suspension with Mouse BD Fc Block™ purified anti-mouse CD16/CD32 mAb 2.4G2 (eg, ≤ 1 μg/million cells in 100 μl) at 4?C for 5 minutes.

2. Add antibody of interest directly to preincubated cells in the presence of Mouse BD Fc Block™ (ie, Mouse BD Fc Block™ need not be washed off before staining cells).

3. If anti-Ig second-step is necessary, a reagent must be chosen which will not bind to Mouse BD Fc Block™ (eg, rat IgG2b, κ).
