Rabex-5 Antibody in Immunohistochemistry (IHC) — Immunohistochemistry of RABEX5 in mouse brain tissue with Rabex-5 Polyclonal Antibody (Product # PA5-21117) at 5 µg/mL.

Rabex-5 Antibody in Western Blot (WB) — Western Blot analysis of RABEX5 in human liver tissue lysate with Rabex-5 Polyclonal Antibody (Product # PA5-21117) at (A) 1 and (B) 2 µg/mL.

Rabex-5 Antibody — Figure 8--figure supplement 1. Silencing synaptic activity affects synaptic levels of endosome proteins in Pclo wt/wt and Pclo gt/gt neurons. ( A and B ) Images of Pclo wt/wt ( A ) and Pclo gt/gt ( B ) neurons stained for Synaptophysin and Rab5 with and without TTX treatment. ( C ) Quantification of ( A and B ). Synaptic Rab5 levels do not significantly alter in Pclo wt/wt and Pclo gt/gt synapses upon TTX treatment ( Pclo wt/wt = 1 +- 0.05, n = 391 synapses; Pclo wt/wt (TTX) = 0.73 +- 0.05, n = 482 synapses; Pclo gt/gt = 1.14 +- 0.09, n = 400 synapses; Pclo gt/gt (TTX) = 0.90 +- 0.04, n = 372 synapses; two independent experiments). ( D and E ) Images of Pclo wt/wt ( D ) and Pclo gt/gt ( E ) neurons stained for Synaptophysin and EEA1 with and without TTX treatment. ( F ) Quantification of ( D and E ). In Pclo wt/wt synapses EEA1 levels drop upon TTX treatment ( Pclo wt/wt = 1 +- 0.03, n = 1653 synapse; Pclo wt/wt (TTX) = 0.72 +- 0.03, n = 1887 synapses; four independent experiments). In contrast, EEA1 levels slightly increase in Pclo gt/gt synapses due to TTX treatment ( Pclo gt/gt = 0.68 +- 0.04, n = 918; Pclo gt/gt (TTX) = 0.78 +- 0.03, n = 1352; four independent experiments). ( G and H ) Pclo wt/wt ( G ) and Pclo gt/gt ( H ) neurons stained for Synaptophysin and Rabex5 with and without TTX treatment. ( I ) Quantification of ( G and H ). Rabex5 level at synapses slightly decrease in Pclo wt/wt and Pclo gt/gt neurons upon TTX treatment ( Pclo wt/wt = 1 +- 0.02, n = 2124 punct {TM}

Rabex-5 Antibody in Immunocytochemistry (ICC/IF) — Figure 8--figure supplement 1. Silencing synaptic activity affects synaptic levels of endosome proteins in Pclo wt/wt and Pclo gt/gt neurons.

Product Specific Information

A suggested positive control is rat brain tissue lysate.

PA5-21117 can be used with blocking peptide PEP-1231.

Target Information

RABGEF1 forms a complex with rabaptin-5 (RABPT5) that is required for endocytic membrane fusion, and it serves as a specific guanine nucleotide exchange factor (GEF) for RAB5.
