Remarks	This antibody has been affinity purified with the complete antigen (aa 154 - 227) and recognizes all isoforms, due to the homology of Rab 3 proteins.

Monoclonal mouse antibody against Rab 3a
Cat. No. 107 111 IgG, unlabeled	100 µg purified IgG, lyophilized. For reconstitution add 100 µl H₂O to get a 1mg/ml solution of antibody in PBS. Then aliquot and store at -20°C until use.
Applications	WB: 1 : 1000 (AP staining) blot IP: yes ICC: 1 : 1000 up to 1 : 2000 image IHC: yes
Clone	42.2

Epitope	Localized to a stretch of 20 amino acids in the C-terminal part of the molecule (aa 191 - 220.
Reactivity	Human, rat, mouse, mammals.
Specificity	Specific for mammalian Rab 3a.

Polyclonal rabbit antibody against Rab 3a
Cat. No. 107 102 crude antiserum	200 µl antiserum, lyophilized. For reconstitution add 200 µl H₂O, then aliquot and store at -20°C until use.
Applications	WB: 1 : 1000 (AP staining) blot IP: yes ICC: 1 : 1000 image IHC: yes image
Immunogen	Synthetic peptide ASATDSRYGQKES (aa 2 - 14 in rat Rab 3a) coupled to key-hole limpet hemocyanin via an added N-terminal cysteine residue.
Reactivity	Human, rat, mouse, hamster, cow, zebrafish.
Specificity	Specific for Rab 3a.

Control peptide for Rab 3a rabbit antibody
Cat. No. 107-1P	100 µg lyophilized peptide. For reconstitution add 100 µl H₂O to get a 1mg/ml solution in PBS. Then aliquot and store at -20°C until use. Control peptides should also be stored at -20°C when still lyophilized!
Recommended dilution	Optimal concentrations should be determined by the end-user.
Remarks	This control peptide consists of the synthetic peptide (ASATDSRYGQKES) that has been used for immunization. It has been tested in preadsorption experiments and blocks efficiently and specifically the corresponding signal in Western blots. The amount of peptide needed for efficient blocking depends on the titer and on the affinity of the antibody to the antigen.

Polyclonal rabbit antibody against Rab 3c
Cat. No. 107 203 purified antibody	50 µg specific antibody, lyophilized. Affinity purified with the immunogen. Rabbit serum albumin was added for stabilization. For reconstitution add 50 µl H₂O to get a 1mg/ml solution of antibody in PBS. Then aliquot and store at -20°C until use.
Applications	WB: 1 : 1000 (AP staining) blot IP: yes ICC: 1 : 500 image IHC: not tested yet
Immunogen	Recombinant protein of human Rab 3c (aa 154 - 227).
Reactivity	Human, rat, mouse, cow, monkey.
Specificity	Specific for Rab 3c.
Remarks	This antibody has been affinity purified with a peptide consisting only of the Rab 3c specific epitope NTRLKETPPPPQPN (aa 211 - 224) of the human protein.

Polyclonal rabbit antibody against Rab 3d
Cat. No. 107 303 purified antibody	50 µg specific antibody, lyophilized. Affinity purified with the immunogen. Rabbit serum albumin was added for stabilization. For reconstitution add 50 µl H₂O to get a 1mg/ml solution of antibody in PBS. Then aliquot and store at -20°C until use.
